The networks file contains information about the known networks that
comprise the DARPA (Defense Advanced Research Projects Agency) Inter‐
net. Each network is represented by a single line in the networks file.
The format for the entries in the networks file is as follows: Name
The fields contain the following: The official network name. The net‐
work number. The unofficial names used for the network.
Items on a line are separated by one or more spaces or tab characters.
Comments begin with a # (number sign). Routines that search the net‐
works file do not interpret characters from the beginning of a comment
to the end of that line. Network numbers are specified in dotted-deci‐
mal notation. A network name can contain any printable character
except a field delimiter, newline character, or comment character (#).
The networks file is normally created from the official network data‐
base maintained at the Network Information Center (NIC). The file may
need to be modified locally to include unofficial aliases or unknown
