NAME
networks - network name information
DESCRIPTION
The file
/etc/networks
is a plain ASCII file that describes known DARPA networks and symbolic
names for these networks.
Each line represents a network and has the following structure:
-
name number aliases ...
where the fields are delimited by spaces or tabs.
Empty lines are ignored.
The hash character (#) indicates the start of a comment:
this character, and the remaining characters up to
the end of the current line,
are ignored by library functions that process the file.
The field descriptions are:
- name
-
The symbolic name for the network.
Network names can contain any printable characters except
white-space characters or the comment character.
- number
-
The official number for this network in numbers-and-dots notation (see
inet(3)).
The trailing ".0" (for the host component of the network address) may be omitted.
- aliases
-
Optional aliases for the network.
This file is read by the
route(8)
and
netstat(8)
utilities.
Only Class A, B or C networks are supported, partitioned networks
(i.e., network/26 or network/28) are not supported by this file.
