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 execept white-space characters or the
number The official number for this network in numbers-and-dots nota-
tion (see inet(3)). The trailing ".0" (for the host component
of the network address) may be omitted.
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., net-
work/26 or network/28) are not supported by this facility.
The networks definition file.
getnetbyaddr(3), getnetbyname(3), getnetent(3), netstat(8), route(8)
