This memo is an official status report on the network numbers used in the Internet community. Distribution of this memo is unlimited.


The responsibility for the assignment of IP numbers and ASNs has been assumed by Hostmaster at the DDN Network Information Center (NIC). The Hostmaster staff are indebted to Dr. Jon Postel and Ms. Joyce Reynolds of the Information Sciences Institute at the University of Southern California for their ongoing assistance.

This Network Working Group Request for Comments documents the currently assigned network numbers and gateway autonomous systems. This RFC will be updated periodically, and in any case current information can be obtained from Hostmaster.

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" [32]. The more prominent and more generally used are documented in the "DDN Protocol Handbook" [12] prepared by the NIC. Other collections of older or obsolete protocols are contained in the "Internet Protocol Transition Workbook" [13], or in the "ARPANET Protocol Transition Handbook" [14]. For further information on ordering the complete 1985 DDN Protocol Handbook, contact the Hostmaster.

RFC 1020 Internet Numbers November 1987

The entries 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") cites the handle of the responsible person. The NIC Handle is a unique identifier that is used in the NIC WHOIS (NICNAME) service. People sometimes change electronic mailboxes. To find out the latest mailbox or phone number of a contact, use the NIC WHOIS/NICNAME server or contact HOSTMASTER@SRI-NIC.ARPA.

The convention used for the documentation of Internet Protocols is to express numbers in decimal and to picture data in "big-endian" order [31]. 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. Fo...
