NAME
networks - network name database
/etc/inet/networks
/etc/networks
DESCRIPTION
The networks file is a local source of information regarding
the networks which comprise the Internet. The networks
file can be used in conjunction with, or instead of, other
networks sources, including the NIS maps networks.byname and
networks.byaddr and the NIS+ table networks. Programs use
the getnetbyname(3N) routines to access this information.
The network file has a single line for each network, with
the following information:
official-network-name network-number aliases
Items are separated by any number of SPACE and/or TAB char-
acters. A `#' indicates the beginning of a comment; charac-
ters up to the end of the line are not interpreted by rou-
tines which search the file. This file is normally created
from the official network 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 networks.
Network numbers may be specified in the conventional dot
(`.') notation using the inet_network routine from the
Internet address manipulation library, inet(7). Network
names may contain any printable character other than a field
delimiter, NEWLINE, or comment character.

file. The symbolic link /etc/networks exists for BSD compa-
