NAME
networks — network name data base
DESCRIPTION
The
/etc/networks
file associates Internet (IP) addresses
with official network names and aliases.
This allows the user to refer to a network by a symbolic name
instead of using an Internet address.
For each network, a single line should be present
with the following information:
<official network name> <network number> <aliases>
Aliases are other names under which a network is known.
For example:
where the network named
loop
is also called
testlan.
A line cannot start with a blank (tab or space character).
Items are separated by any number or combination of blanks.
A
#
character indicates the beginning of a comment.
Characters from the
#
up to the end of the line
are not interpreted by routines which search the file.
Trailing blanks are allowed at the end of a line.
For the Internet,
this file is normally 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.
Network numbers can be specified
in conventional Internet dot notation using the
inet_network()
routine from the internet address manipulation library (see
inet(3N).
Network names can contain any printable character
other than a white space, new-line, or comment character.
