/etc/networks

[fellons]

Hi list.

On my FC2 server I have eth0 and lo network interfaces.
Reply correctly to ping (to 127.0.0.1 and 192.168.0.1 ... ).
Are correct routing and /etc/hosts too.

On guide from installing domestic networks than I have read, apropos
to DNS, it mention /etc/networks like a file to recognize network
ip-name (!?).

On my configuration I don't use DNS, I use only ../hosts.

Questions:
/etc/networks must there is or not ?
and must declare :
localdomain 127.0.01
home.bear.net 192.168.0.0  ??

Thanks to any reply
