Network name information
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:
The symbolic name for the network. Network names can contain any printable characters except white-space characters or the comment character.
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.
Optional aliases for the network.
The networks definition file.
