 The "region" was used for administrative purposes, and was only part of the address if the node was listed directly underneath the Regional Coordinator, rather than one of the networks that were used to divide the region further.FidoNet policy requires that each FidoNet system maintain a "nodelist" of every other member system.Information on each node includes the name of the system or BBS, the name of the node operator, the geographic location, the telephone number, and software capabilities.
