This RFC will be updated periodically, and in any case current information can be obtained from the Internet Assigned Numbers Authority (IANA). 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 Joyce K.

ISI.EDU Most of the protocols mentioned here 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 "IAB Official Protocol Standards" [62]. In the entries below , the name and mailbox of the responsible individual is indicated. The bracketed entry, eg, [nn, iii], at the right hand margin of the page indicates a reference for the listed protocol, where the number ( "nn") cites the Document and the Letters ("III") CITES The Person. WHENEVER POSSIBLE, The Letters Are A Nic Ident As Used In The WHOIS (NICName) Service. Reynolds & Postel [Page 2]
RFC 1340 Assigned Numbers July 1992 Data Notations The convention in the documentation of Internet Protocols is to express numbers in decimal and to picture data in "big-endian" order [21]. 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 The FOLLISH. For Example, In The Following Diagram The Octets Are Trance. 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 a multi-octet quantity is transmitted the most significant octet is transmitted first.

RFC 1340 Assigned Numbers July 1992 Special Addresses: There are five classes of IP addresses:.. Class A through Class E [119] Of these, Class E addresses are reserved for experimental use A gateway which is not participating in these experiments must ignore all datagrams with a Class E destination IP address. ICMP Destination Unreachable or ICMP Redirect messages must not result from receiving such datagrams. There are certain special cases for IP addresses [11]. These special cases can be concisely summarized using the earlier notation for an IP Address: ip-address :: = {

RFC 1340 Assigned Numbers July 1992 WELL KNOWN PORT NUMBERS 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 [45,106] 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 [46,104]. 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.

RFC 1340 Assigned Numbers July 1992 REGISTERED PORT NUMBERS 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 [45,106] 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 [46,104] The Registered Ports are in the range 1024-65535 Port Assignments:

RFC 1340 Assigned Numbers July 1992 IP TOS PARAMETERS This documents the default Type-of-Service values that are currently recommended for the most important Internet protocols There are four assigned TOS values: low delay, high throughput, high reliability, and low cost;. in each case, 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 Decimail, 0100 binary). The Following Are Recommended Values for Tos: ----- Type-of-Service Value ----- Protocol TOS Value Telnet (1) 1000 (Minimize Delay) FTP Con trol 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 30]

RFC 1340 Assigned Numbers July 1992 NETWORK MANAGEMENT PARAMETERS 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) RFC-1157 [15], or the" Common Management Information Protocol over TCP "(CMOT) [142]. The data structure is the" Structure and Indentification of Management Information for TCP / IP-based Internets "( SMI) RFC-1155 [120], and the "Management Information Base for Network Management of TCP / IP-based Internets" (MIB-II) [121]. 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) RFC-1028 [37] also defined a data structure. The parameter assignments used with SGMP are included here for hist orical completeness.
