Most of the protocols used in the Internet 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 "Official Internet Protocols" [40]. The more prominent and more generally used are documented in the "DDN Protocol Handbook" [17] prepared by the NIC. Other collections of older or obsolete protocols are contained in the "Internet Protocol Transition Workbook" [18], or in the "ARPANET Protocol Transition Handbook" [19]. For further information on ordering the complete 1985 DDN Protocol Handbook, contact the Hostmaster. Also, the Internet Activities Board (IAB) publishes the "IAB Official Protocol Standards" [52], which describes the state of standardization of protocols used in the Internet. This document is issued quarterly. Current copies may be obtained from the DDN Network Information Center.

RFC 1117 Internet Numbers August 1989

The lists below contain the name and network mailbox of the individuals responsible for each registered network or autonomous system. The bracketed entry, e.g., [nn,iii], at the right hand margin of the page indicates a reference for the listed network or autonomous system, where the number ("nn") cites the document and the letters ("iii") cite the NIC Handle of the responsible person. The NIC Handle is a unique identifier that is used in the NIC WHOIS/NICNAME service. People occasionally change electronic mailboxes. To find out the current network mailbox or phone number for an individual, or to get information about a registered network, use the NIC WHOIS/NICNAME service or contact HOSTMASTER@NIC.DDN.MIL.

The convention used for the documentation of Internet Protocols is to express numbers in decimal and to picture data in "big-endian" order [39]. 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. Whene...
