Abstract

This document describes the current status of the development and deployment of CIDR technology into the Internet. This document replaces RFC 1367, which was a schedule for the deployment of IP address space management procedures to support route aggregation. Since all the milestones proposed in RFC 1367 except for the delivery and installation of CIDR software were met, it does not seem appropriate to issue an updated schedule. Rather, this document is intended to provide information about how this effort is proceeding, which may be of interest to the community.

1. Background

The Internet’s exponential growth has led to a number of difficulties relating to the management of IP network numbers. The administrative overhead of allocating ever increasing volumes of IP network numbers for global users has stressed the organizations that perform this function. The volume of IP network numbers that are reachable through the Internet has taxed a number of routers’ ability to manage their forwarding tables. The poor utilization of allocated IP network numbers has threatened to deplete the Class A and Class B address space.

During the past few years, a consensus has emerged among the Internet community in favor of a number of mechanisms to relieve these problems for the mid-term. These mechanisms are expected to be put into place in the short term and to provide relief for the mid-term. Fundamental changes to the Internet protocols to ensure the Internet’s continued long term growth and well being are being explored and are expected to succeed the mid-term mechanisms.

The global Internet community have been cooperating closely in such forums as the IETF and its working groups, the IEPG, the NSF Regional Techs Meetings, INET, INTEROP, FNC, FEPG, and other assemblies in

order to ensure the continued stable operation of the Internet. Recognizing the need for the mid-term mechanisms and receiving support from the Internet community, the US Federal Agencies proposed procedures to assist the deployment of these mid-term mechanisms. These procedures were originally described in RFC 1366 [1], which was recently made obsolete by RFC 1466 [2]. In October 1992, a schedule was proposed for the implementation of the procedures, described in RFC 1367 [3].

2. Milestones that have been met

Most of the milestones of the proposed schedule were implemented on time. These milestones are shown below, essentially as they appear in [3], but with further comment where appropriate:
