                          ASSIGNED NUMBERS

Status of this Memo

 This memo is a status report on the parameters (i.e., numbers and
 keywords) used in protocols in the Internet community.  Distribution
 of this memo is unlimited.


This RFC is a snapshot of the ongoing process of the assignment of protocol parameters for the Internet protocol suite. To make the current information readily available the assignments are kept up-to- date in a set of online text files. This RFC has been assembled by catinating these files together with a minimum of formatting "glue". The authors appologize for the somewhat rougher formatting and style than is typical of most RFCs.

We expect that various readers will notice specific items that should be corrected. Please send any specific corrections via email to

Reynolds & Postel [Page 1] RFC 1700 Assigned Numbers October 1994


The files in this directory document the currently assigned values for several series of numbers used in network protocol implementations.

The Internet Assigned Numbers Authority (IANA) is the central coordinator for the assignment of unique parameter values for Internet protocols. The IANA is chartered by the Internet Society (ISOC) and the Federal Network Council (FNC) to act as the clearinghouse to assign and coordinate the use of numerous Internet protocol parameters.

The Internet protocol suite, as defined by the Internet Engineering Task Force (IETF) and its steering group (the IESG), contains numerous parameters, such as internet addresses, domain names, autonomous system numbers (used in some routing protocols), protocol numbers, port numbers, management information base object identifiers, including private enterprise numbers, and many others.

The common use of the Internet protocols by the Internet community requires that the particular values used in these parameter fields be assigned uniquely. It is the task of the IANA to make those unique assignments as requested and to maintain a registry of the currently assigned values.

Requests for parameter assignments (protocols, ports, etc.) should be sent to

Requests for SNMP network management private enterprise number assignments should be sent to

The IANA is located at and operated by the Information Sciences Institute (ISI) of the University of Southern California (USC).

If you are developing a protocol or application that will require the use of a link, socket, port, protocol, etc., please contact the IANA to receive a number assignment.

Most of the protocols are documented in the RFC series of notes. Some of the items listed are undocumented. Further information on protocols can be found in the memo, "Internet Official Protocol Standards" (STD 1).

Data Notations

The convention in the documentation of Internet Protocols is to express numbers in decimal and to picture data in "big-endian" order [COHEN]. That is, fields are described left to right, with the most significant octet on the left and the least significant octet on the right.

The order of transmission of the header and data described in this document is resolved to the octet level. Whenever a diagram shows a group of octets, the order of transmission of those octets is the normal order in which they are read in English. For example, in the following diagram the octets are transmitted in the order they are numbered.

  0                   1                   2                   3
  0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
 |       1       |       2       |       3       |       4       |
 |       5       |       6       |       7       |       8       |
 |       9       |      10       |      11       |      12       |
                     Transmission Order of Bytes

Whenever an octet represents a numeric quantity the left most bit in the diagram is the high order or most significant bit. That is, the bit labeled 0 is the most significant bit. For example, the following diagram represents the value 170 (decimal).

                        0 1 2 3 4 5 6 7
                       |1 0 1 0 1 0 1 0|
                      Significance of Bits

Similarly, whenever a multi-octet field represents a numeric quantity the left most bit of the whole field is the most significant bit. When

Reynolds & Postel [Page 3] RFC 1700 Assigned Numbers October 1994

a multi-octet quantity is transmitted the most significant octet is transmitted first.

Special Addresses

There are five classes of IP addresses: Class A through Class E. Of these, Classes A, B, and C are used for unicast addresses, Class D is used for multicast addresses, and Class E addresses are reserved for future use.

With the advent of classless addressing [CIDR1, CIDR2], the network-number part of an address may be of any length, and the whole notion of address classes becomes less important.

There are certain special cases for IP addresses. These special cases can be concisely summarized using the earlier notation for an IP address:

    IP-address ::=  { <Network-number>, <Host-number> }
    IP-address ::=  { <Network-number>, <Subnet-number>,
                                                    <Host-number> }

if we also use the notation "-1" to mean the field contains all 1 bits. Some common special cases are as follows:

    (a)   {0, 0}
       This host on this network.  Can only be used as a source
       address (see note later).
    (b)   {0, <Host-number>}
       Specified host on this network.  Can only be used as a
       source address.
    (c)   { -1, -1}
       Limited broadcast.  Can only be used as a destination
       address, and a datagram with this address must never be
       forwarded outside the (sub-)net of the source.
    (d)   {<Network-number>, -1}
       Directed broadcast to specified network.  Can only be used
       as a destination address.

Reynolds & Postel [Page 4] RFC 1700 Assigned Numbers October 1994

    (e)   {<Network-number>, <Subnet-number>, -1}
       Directed broadcast to specified subnet.  Can only be used as
       a destination address.
    (f)   {<Network-number>, -1, -1}
       Directed broadcast to all subnets of specified subnetted
       network.  Can only be used as a destination address.
    (g)   {127, <any>}
       Internal host loopback address.  Should never appear outside
       a host.

Reynolds & Postel [Page 15] RFC 1700 Assigned Numbers October 1994


The Well Known Ports are controlled and assigned by the IANA and on most systems can only be used by system (or root) processes or by programs executed by privileged users.

Ports are used in the TCP [RFC793] to name the ends of logical connections which carry long term conversations. For the purpose of providing services to unknown callers, a service contact port is defined. This list specifies the port used by the server process as its contact port. The contact port is sometimes called the "well-known port".

To the extent possible, these same port assignments are used with the UDP [RFC768].

The assigned ports use a small portion of the possible port numbers. For many years the assigned ports were in the range 0-255. Recently, the range for assigned ports managed by the IANA has been expanded to the range 0-1023.

Port Assignments:

The Registered Ports are not controlled by the IANA and on most systems can be used by ordinary user processes or programs executed by ordinary users.

Ports are used in the TCP [RFC793] to name the ends of logical connections which carry long term conversations. For the purpose of providing services to unknown callers, a service contact port is defined. This list specifies the port used by the server process as its contact port. While the IANA can not control uses of these ports it does register or list uses of these ports as a convienence to the community.

To the extent possible, these same port assignments are used with the UDP [RFC768].

The Registered Ports are in the range 1024-65535.

Reynolds & Postel [Page 60] RFC 1700 Assigned Numbers October 1994


To obtain SUN Remote Procedure Call (RPC) numbers send an e-mail request to "".

The RPC port management service ('portmap' in SunOS versions less than 5.0 and 'rpcbind' in SunOS versions greater than 5.0) "registers" the IP port number that is allocated to a particular service when that service is created. It does not allocate ports on behalf of those services.

For an exact specification of the semantics refer to the source code of svcudp_create() and svctcp_create() in the archives. In short however is that these interfaces, and svc_tli_create their Transport Independent RPC equivalent, take either a user specified port number or RPC_ANY (-1) which effectively means "I don't care." In the "I don't care" case the create code simply calls socket(2) or t_open(3n) which allocates an IP port based on the rules:

      if euid of the requesting process is 0 (i.e., root)
              allocate the next available port number in the
              reserved port range.
              allocate the next available port in the non-reserved

Port numbers count up sequentially.

Can a port that is "assigned" can be used when the assignee's service is not present? Say port 501 is assigned to the "jeans" service. On a machine that does not have the "jeans" service, nor has any clients that might be expecting to use it, is port 501 available for other uses? Any dynamic allocation process, like the portmapper, that chooses the next unused port might allocate port 501 dynamically to a process that asked for a "I don't care" port. So any dynamic allocation scheme may pick an unused port that happened to correspond to a port number that had been "assigned" but was currently unused.

While it might be desirable, it is impossible to guarantee that any unused port, even though officially assigned to a service, is not picked by a dynamic allocator since such an assignment might occur long after the delivery of the system into a site that doesn't watch for the latest list.

There is the restriction that only "superuser" on BSD derived systems such as SunOS can bind to a port number that is less than 1024. So programs have used this information in the past to identify whether or

Reynolds & Postel [Page 61] RFC 1700 Assigned Numbers October 1994

not the service they were talking to was started by the superuser on the remote system. Making this assumption is dangerous because not all system enforce this restriction.

Sun RPC services use ports that are currently unused. If someone noted that an RPC service was using port 781, it would be just as happy using port 891, or 951. The service doesn't care what port it gets, remote clients will query the portmapper to ask it what port number was assigned to the service when it was started. The key is that the port was not currently in use. The only port that ONC/RPC must have is 111 its assigned port for the portmap service.

The most common complaint comes when people put a new service on their system. When they configure their systems they put the new service configuration commands at the end of their system startup scripts. During startup, several network services may be started. Those services that are ONC/RPC based just pick the next available port, those that have pre-assigned ports bind to their pre-assigned port. Clearly the correct sequence is to have all services that need a particular port to be started first (or if they are "latent" services that are started by inetd, to have inetd started). Finally, the RPC services should be started as they will be assigned unused ports. (In the BSD networking code (which we use) the algorithm for picking ports is in the file in_pcb.c, function in_pcbbind().)

Services should be started in this order:

 a) Services that will "run" continuously and have an assigned
    port. Note that this includes rpcbind (nee portmap) that has
    port 111 assigned to it.
 b) inetd - which will automatically create sockets for those
    services that have reserved ports but only run on demand
    (like finger)
 c) RPC services - which will automatically pick unused ports and
    maximize efficiency of the "IP Port" namespace.

The include file /usr/include/netinet/in.h defines a constant IPPORT_RESERVED to be 1024. The relevant text is:

  * Ports < IPPORT_RESERVED are reserved for
  * privileged processes (e.g. root).
  * Ports > IPPORT_USERRESERVED are reserved
  * for servers, not necessarily privileged.
 #define IPPORT_RESERVED         1024

Reynolds & Postel [Page 62] RFC 1700 Assigned Numbers October 1994

 #define IPPORT_USERRESERVED     5000

Portmap does not allocate ports, the kernel allocates ports. The code that does this is part of nearly every UNIX system in the world (and since the BSD code is 'free' it is often the same code). RPC services ask the kernel to allocate them a port by calling the "bind()" system call. The parameter they pass is "INADDR_ANY" which means "allocate me any IP port you want". The kernel does that by looking at all of the ports that are currently in use and picking one that is not currently used. The number picked is either less that 1024 if the process is privledged, or greater than 1024 if the process is not privledged. After the kernel has allocated a port, the service registers this allocation with portmap. The portmapper is merely a registry of previously allocated ports. Note "allocated" here is being used in the sense that they are used by an open socket, not assigned a well known name.

The role of /etc/services is to provide an idea to people who are looking at network traffic as to where a packet may have originated from or is headed to. For services like finger that have assigned ports, they can just hard code the port they want into their executable. (it isn't like it will change, and if they read it from /etc/services and someone had mistyped the port number it won't interoperate with clients anyway!)

It is not practical to read the /etc/services file into the kernel to prevent it from giving out port numbers that are "pre-assigned", nor is it generally desirable since with the correct ordering of startup it is completely unneccesary.

The Internet Protocol (IP) has provision for optional header fields identified by an option type field. Options 0 and 1 are exactly one octet which is their type field. All other options have their one octet type field, followed by a one octet length field, followed by length-2 octets of option data. The option type field is sub-divided into a one bit copied flag, a two bit class field, and a five bit option number. These taken together form an eight bit value for the option type field. IP options are commonly refered to by this value.

The current recommended default time to live (TTL) for the Internet Protocol (IP) [45,105] is 64.


This documents the default Type-of-Service values that are currently recommended for the most important Internet protocols.

Reynolds & Postel [Page 64] RFC 1700 Assigned Numbers October 1994

TOS Value Description Reference ——— ————————– ———

0000          Default                                 [RFC1349]
0001          Minimize Monetary Cost                  [RFC1349]

1111          Maximize Security                       [RFC1455]

The TOS value is used to indicate "better". Only one TOS value or property can be requested in any one IP datagram.

Generally, protocols which are involved in direct interaction with a human should select low delay, while data transfers which may involve large blocks of data are need high throughput. Finally, high reliability is most important for datagram-based Internet management functions.

Application protocols not included in these tables should be able to make appropriate choice of low delay (8 decimal, 1000 binary) or high throughput (4 decimal, 0100 binary).

The following are recommended values for TOS:

  1. —- Type-of-Service Value —–

Protocol TOS Value

TELNET (1) 1000 (minimize delay)


Control          1000                 (minimize delay)
Data (2)         0100                 (maximize throughput)

TFTP 1000 (minimize delay)

SMTP (3)

Command phase    1000                 (minimize delay)
DATA phase       0100                 (maximize throughput)

Domain Name Service

UDP Query        1000                 (minimize delay)
TCP Query        0000
Zone Transfer    0100                 (maximize throughput)

NNTP 0001 (minimize monetary cost)


Reynolds & Postel [Page 65] RFC 1700 Assigned Numbers October 1994

Errors           0000
Requests         0000 (4)
Responses        <same as request> (4)

Any IGP 0010 (maximize reliability)

EGP 0000

SNMP 0010 (maximize reliability)

BOOTP 0000


(1) Includes all interactive user protocols (e.g., rlogin).

(2) Includes all bulk data transfer protocols (e.g., rcp).

(3) If the implementation does not support changing the TOS during the lifetime of the connection, then the recommended TOS on opening the connection is the default TOS (0000).

(4) Although ICMP request messages are normally sent with the default TOS, there are sometimes good reasons why they would be sent with some other TOS value. An ICMP response always uses the same TOS value as was used in the corresponding ICMP request message.

An application may (at the request of the user) substitute 0001 (minimize monetary cost) for any of the above values.

The Bootstrap Protocol (BOOTP) [RFC951] describes an IP/UDP bootstrap protocol (BOOTP) which allows a diskless client machine to discover its own IP address, the address of a server host, and the name of a file to be loaded into memory and executed. The Dynamic Host Configuration Protocol (DHCP) [RFC1531] provides a framework for automatic configuration of IP hosts. The "DHCP Options and BOOTP Vendor Information Extensions" [RFC1533] describes the additions to the Bootstrap Protocol (BOOTP) which can also be used as options with the Dynamic Host Configuration Protocol (DHCP).

BOOTP Vendor Extensions and DHCP Options are listed below:

Reynolds & Postel [Page 100] RFC 1700 Assigned Numbers October 1994


These are the official names for character sets that may be used in the Internet and may be referred to in Internet documentation. These names are expressed in ANSI_X3.4-1968 which is commonly called US-ASCII or simply ASCII. The character set most commonly use in the Internet and used especially in protocol standards is US-ASCII, this is strongly encouraged. The use of the name US-ASCII is also encouraged.

The character set names may be up to 40 characters taken from the printable characters of US-ASCII. However, no distinction is made between use of upper and lower case letters.

Reynolds & Postel [Page 118] RFC 1700 Assigned Numbers October 1994


For the management of hosts and gateways on the Internet a data structure for the information has been defined. This data structure should be used with any of several possible management protocols, such as the "Simple Network Management Protocol" (SNMP) [RFC1157], or the "Common Management Information Protocol over TCP" (CMOT) [RFC1095].

The data structure is the "Structure and Indentification of Management Information for TCP/IP-based Internets" (SMI) [RFC1155], and the "Management Information Base for Network Management of TCP/IP-based Internets" (MIB-II) [RFC1213].

The SMI includes the provision for panrameters or codes to indicate experimental or private data structures. These parameter assignments are listed here.

The older "Simple Gateway Monitoring Protocol" (SGMP) [RFC1028] also defined a data structure. The parameter assignments used with SGMP are included here for historical completeness.

The network management object identifiers are under the iso (1), org (3), dod (6), internet (1), or, branch of the name space.

The major branches are:

1 iso 1.3 org 1.3.6 dod internet directory mgmt mib-2 ifType transmission transmission.ppp application mta experimental private enterprise security SNMPv2 mail

  1. - OIDs of the form {applTCPProtoID port} are intended to be used
  2. - for TCP-based protocols that don't have OIDs assigned by other
  3. - means. {applUDPProtoID port} serves the same purpose for
  4. - UDP-based protocols. In either case 'port' corresponds to

  6. - assuming no other OID is assigned for SMTP, an OID of
  7. - {applTCPProtoID 25} could be used, since SMTP is a TCP-based
  8. - protocol that uses port 25 as its primary port.

Reynolds & Postel [Page 165] RFC 1700 Assigned Numbers October 1994


Some of the networks of all classes are IEEE 802 Networks. These systems may use a Link Service Access Point (LSAP) field in much the same way the MILNET uses the "link" field. Further, there is an extension of the LSAP header called the Sub-Network Access Protocol (SNAP).

The IEEE likes to describe numbers in binary in bit transmission order, which is the opposite of the big-endian order used throughout the Internet protocol documentation.

The standard for transmission of IP datagrams over Ethernets and Experimental Ethernets is specified in [RFC894] and [RFC895] respectively.

Reynolds & Postel [Page 171] RFC 1700 Assigned Numbers October 1994

NOTE: Ethernet 48-bit address blocks are assigned by the IEEE.

The IANA owns an Ethernet address block which may be used for multicast address asignments or other special purposes.

The address block in IEEE binary is: 0000 0000 0000 0000 0111 1010

In the normal Internet dotted decimal notation this is 0.0.94 since the bytes are transmitted higher order first and bits within bytes are transmitted lower order first (see "Data Notation" in the Introduction).

IEEE CSMA/CD and Token Bus bit transmission order: 00 00 5E

IEEE Token Ring bit transmission order: 00 00 7A

The latter representation corresponds to the Internet standard bit-order, and is the format that most programmers have to deal with. Using this representation, the range of Internet Multicast addresses is:

     01-00-5E-00-00-00  to  01-00-5E-7F-FF-FF  in hex, or  to  in dotted decimal


Ethernet hardware addresses are 48 bits, expressed as 12 hexadecimal digits (0-9, plus A-F, capitalized). These 12 hex digits consist of the first/left 6 digits (which should match the vendor of the Ethernet interface within the station) and the last/right 6 digits which specify the interface serial number for that interface vendor.

Ethernet addresses might be written unhyphenated (e.g., 123456789ABC), or with one hyphen (e.g., 123456-789ABC), but should be written hyphenated by octets (e.g., 12-34-56-78-9A-BC).

These addresses are physical station addresses, not multicast nor broadcast, so the second hex digit (reading from the left) will be even, not odd.

At present, it is not clear how the IEEE assigns Ethernet block addresses. Whether in blocks of 224 or 225, and whether multicasts are assigned with that block or separately. A portion of the vendor block address is reportedly assigned serially, with the other portion intentionally assigned randomly. If there is a global algorithm for which addresses are designated to be physical (in a chipset) versus logical (assigned in software), or globally-assigned versus locally-assigned addresses, some of the known addresses do not follow the scheme (e.g., AA0003; 02xxxx).

An Ethernet multicast address consists of the multicast bit, the 23-bit vendor component, and the 24-bit group identifier assigned by the vendor. For example, DEC is assigned the vendor component 08-00-2B, so multicast addresses assigned by DEC have the first 24-bits 09-00-2B (since the multicast bit is the low-order bit of the first byte, which is "the first bit on the wire").

Reynolds & Postel [Page 185] RFC 1700 Assigned Numbers October 1994


The word "link" here refers to a field in the original MILNET Host/IMP interface leader. The link was originally defined as an 8-bit field. Later specifications defined this field as the "message-id" with a length of 12 bits. The name link now refers to the high order 8 bits of this 12-bit message-id field. The Host/IMP interface is defined in BBN Report 1822 [BBN1822].

The low-order 4 bits of the message-id field are called the sub-link. Unless explicitly specified otherwise for a particular protocol, there is no sender to receiver significance to the sub-link. The sender may use the sub-link in any way he chooses (it is returned in the RFNM by the destination IMP), the receiver should ignore the sub-link.

The MILNET facility for "logical addressing" is described in [RFC878] and [RFC1005]. A portion of the possible logical addresses are reserved for standard uses.

There are 49,152 possible logical host addresses. Of these, 256 are reserved for assignment to well-known functions. Assignments for well-known functions are made by the IANA. Assignments for other

All MILNET hosts are assigned addresses by the Defense Data Network (DDN). The address of a MILNET host may be obtained from the Network Information Center (NIC), represented as an ASCII text string in what is called "host table format". This section describes the process by which MILNET X.25 addresses may be derived from addresses in the NIC host table format.

A NIC host table address consists of the ASCII text string representations of four decimal numbers separated by periods, corresponding to the four octeted of a thirty-two bit Internet address. The four decimal numbers are referred to in this section as "n", "h' "l", and "i". Thus, a host table address may be represented as: "n.h.l.i". Each of these four numbers will have either one, two, or three decimal digits and will never have a value greater than 255. For example, in the host table, address: "", n=10, h=2, l=0, and i=124. To convert a host table address to a MILNET X.25 address:

1. If h < 64, the host table address corresponds to the X.25 physical address:



   ZZZZ = 0000    as required
   F = 0          because the address is a physical address;
   III            is a three decimal digit respresentation of
                  "i", right-adjusted and padded with leading

Reynolds & Postel [Page 187] RFC 1700 Assigned Numbers October 1994

                  zeros if required;
   HH             is a two decimal digit representation of "h",
                  right-adjusted and padded with leading zeros
                  if required;
   ZZ = 00        and
   (SS)           is optional

In the example given above, the host table address corresponds to the X.25 physical address 000001240200.

2. If h > 64 or h = 64, the host table address corresponds to the X.25 logical address



   ZZZZ = 0000    as required
   F = 1          because the address is a logical address;
   RRRRR          is a five decimal digit representation of
                  the result "r" of the calculation
                           r = h * 256 + i
                  (Note that the decimal representation of
                  "r" will always require five digits);
   ZZ = 00        and
   (SS)           is optional

Thus, the host table address corresponds to the X.25 logical address 000012145500.

In both cases, the "n" and "l" fields of the host table address are not used.

Below is the current list of PRONET 80 Type Numbers. Note: a protocol that is on this list does not necessarily mean that there is any implementation of it on ProNET.

Of these, protocols 1, 14, and 20 are the only ones that have ever been seen in ARP packets.

For reference, the header is (one byte/line):

      destination hardware address
      source hardware address
      data link header version (2)
      data link header protocol number
      data link header reserved (0)
      data link header reserved (0)

Some protocols have been known to tuck stuff in the reserved fields.

Those who need a protocol number on ProNET-10/80 should contact John Shriver (

The Point-to-Point Protocol (PPP) Data Link Layer [146,147,175] contains a 16 bit Protocol field to identify the the encapsulated protocol. The Protocol field is consistent with the ISO 3309 (HDLC) extension mechanism for Address fields. All Protocols MUST be assigned such that the least significant bit of the most significant octet equals "0", and the least significant bit of the least significant octet equals "1".

Protocol field values in the "0xxx" to "3xxx" range identify the network-layer protocol of specific datagrams, and values in the "8xxx" to "bxxx" range identify datagrams belonging to the associated Network Control Protocol (NCP), if any.

It is recommended that values in the "02xx" to "1exx" and "xx01" to "xx1f" ranges not be assigned, as they are compression inefficient.

Protocol field values in the "4xxx" to "7xxx" range are used for protocols with low volume traffic which have no associated NCP.

Protocol field values in the "cxxx" to "exxx" range identify datagrams as Control Protocols (such as LCP).


The Point-to-Point Protocol (PPP) Link Control Protocol (LCP), [146] the Compression Control Protocol (CCP), Internet Protocol Control Protocol (IPCP), [147] and other control protocols, contain an 8 bit Code field which identifies the type of packet. These Codes are assigned as follows:
