NAME
networks − network name database
DESCRIPTION
The /etc/networks file contains information regarding DARPA Internet networks with which your DOMAIN node can communicate. For each host a single line should be present with the following information: official network name network number aliases Items are separated by any number of blanks and/or tab characters. A # character indicates the beginning of a comment; characters between a # and the next newline are not interpreted by routines which search the file. This file is normally created from the official host database maintained at the Network Information Control Center (NIC), though local changes may be required to bring it up to date regarding unofficial aliases and/or unknown hosts.
Network numbers are specified in the conventional “.” notation using the inet_network() routine from the Internet address manipulation library, inet(3N). Network names may contain any printable character other than a field delimiter, newline, or comment character.
