I'm a administrator of an isp who has a full class c.
We want to break it in half (255.255.255.128). Currently the cisco router connecting the 188.8.131.52 class to the internet is configured for the full range (it's sitting on .254).
I have a linux box configured to route from the 184.108.40.206 network, with the default gateway set to .254 (the cisco router) and eth0 220.127.116.11 and eth1 18.104.22.168, this seems to route between the 2 networks fine.
My question is we dont seem to be able to get out through the cisco now from the .0 network, does it need to be told that the class c has been broken up now?
