networks -- names and numbers for the Internet

Description

The file /etc/networks lists networks on the Internet. Each line describes a single network and consists of the following blank separated fields:

name number aliases ...

where

name: is the official name of the network. All hosts on the Internet should use the same official name for a given network.
number: is the network number, which serves as part of the Internet address for each host on the Internet. All hosts on the Internet must use the same number for a given network.
aliases...: is a blank-separated list of local aliases for the network.

The routines which search this file ignore comments (portions of lines beginning with ``#'') and blank lines.
