Internet Standard Subnetting Procedure
RFC 950, “Internet Standard Subnetting Procedure”, is an Internet Standard document published in August 1985 by J.C. Mogul, J. Postel. It updates RFC 792. It has since been updated by RFC 6918. The canonical text is published by the RFC Editor.
Abstract
This memo discusses 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. This memo specifies procedures for the use of subnets. These procedures are for hosts (e.g., workstations). The procedures used in and between subnet gateways are not fully described. Important motivation and background information for a subnetting standard is provided in RFC-940. This RFC specifies a protocol for the ARPA-Internet community. If subnetting is implemented it is strongly recommended that these procedures be followed.
What “Internet Standard” means
A mature, widely-implemented specification that has completed the full IETF standards process — the highest maturity level on the standards track.
