NETWORKS(4)NETWORKS(4)NAMEnetworks - network name database
DESCRIPTION
The /etc/networks file contains information regarding the known networks
which comprise the Internet. For each network a single line should be
present with the following information:
o official network name
o network number
o aliases (optional)
Items are separated by any number of blanks and/or tab characters. A
``#'' indicates the beginning of a comment; characters up to the end of
the line are not interpreted by routines which search the file.
Network number may be 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. For
example,
loopback 127 loopback-net
For hosts connected to the Internet, this file can be 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.
FILES
/etc/networks
If the NFS option is installed and NIS is running, the getnetent(3N)
library routines do not access this file.

The Internet name server should be used instead of a static file. A
binary indexed file format should be available for fast access.
