I'm a administrator of an isp who has a full class c.<br />
<br />
We want to break it in half (255.255.255.128). &nbsp;Currently the cisco router connecting the 209.251.112.0 class to the internet is configured for the full range (it's sitting on .254).<br />
<br />
I have a linux box configured to route from the 209.251.112.0 network, with the default gateway set to .254 (the cisco router) and eth0 209.251.112.1 and eth1 209.251.112.129, this seems to route between the 2 networks fine. <br />
<br />
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?<br />
<br />
Thanks,<br />

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
