Toward an Internet standard scheme for subnetting
RFC 940, “Toward an Internet standard scheme for subnetting”, is an Unknown document published in April 1985 by Gateway Algorithms and Data Structures Task Force. The canonical text is published by the RFC Editor.
Abstract
Several sites now contain a complex of local links connected to the Internet via a gateway. The details of the internal connectivity are of little interest to the rest of the Internet. One way of organizing these local complexes of links is to use the same strategy as the Internet uses to organize networks, that is, to declare each link to be an entity (like a network) and to interconnect the links with devices that perform routing functions (like gateways). This general scheme is called subnetting, the individual links are called subnets, and the connecting devices are called subgateways (or bridges, or gateways). This RFC discusses standardizing the protocol used in subnetted environments in the ARPA-Internet.
What “Unknown” means
