How do I route a public Class C network through Comcast router?

We have a public class C network that our company owns, we're moving from T-1 lines to cable, most of my public servers will be moving to a data center, but I still need the public class C network working, can this be done with a home type router in a Comcast connection?

From serverfault Art

• Routing an IP network needs to be done through BGP protocol. So either your ISP let you announce BGP routes yourself, or the ISP does it for you. I'm not a comcast expert, but I doubt that that kind of service is part of their "home" package ;)

  Art : Yes, that's what I thought, and after finally talking to someone in Comcast that understood what I was talking about you're correct they do not do it. Thanks!

  Kevin M : Consider marking the above as an Accepted Answer by clicking the outline of a checkmark next to it. This will enable future people with the same problem to know immediately what the resolution is.

• Technically, I don't see that it would be a problem. I suggest talking to your service manager about your needs for routing to your own /24 over whatever infrastructure your new ISP will hook you up to.

• That pretty much is it - no way. You can route whatever you want, but unless the ISP supports it this is like trying to order a mercedes by calling a pizza service - it will get you nowhere.

  What you route through YOUR router is totally irrelevant unless the ISP forwards the packets fourther.

  Now, let's see:

  We have a public class C network that our company owns

  No. You dont own anyxthing - noone does. IP ddresses are not owned, they are assigned like a rental car. That said, a C network is NEVER assigned to someone - RIPE's smallest block that one can get assigned is 4096 IP Addresses. You got a C network from your provider for use with them. YOu kill your provider - the C network gets back to the provider, much as you return a car from a rental agency when you end the rental.

  Art : Actually, you're correct, we do not own the /24 but it is assigned to our company. We have moved before and always have carried the same /24 range with us and when you look it up it's assigned to us so, if we can get someone to route it the range will be out until we do.

  TomTom : Ah. Seriously. No, you can not. A /24 IS NOT INTERNATIONALLY ROUTABLE. When you "moved" you must have moved within THE SAME ISP. You can not switch providers with a /24. Check the owner of your ISP on the IP Authority WHOIS database for your country.

  dbasnett : It sure sounds like Art is in the USA and may have obtained his block from ARIN. If that is so then he can move it anywhere in the USA, with the assistance of his current ISP.
