Abstract

Overview

We discuss the utility of "subnets" of Internet networks, which are logically visible sub-sections of a single Internet network. For administrative or technical reasons, many organizations have chosen to divide one Internet network into several subnets, instead of acquiring a set of Internet network numbers.

We propose procedures for the use of subnets, and discuss approaches to solving the problems that arise, particularly that of routing.

Acknowledgment

This proposal is the result of discussion with several other people. J. Noel Chiappa, Chris Kent, and Tim Mann, in particular, provided important suggestions.
