Comcast Internet IP Address

Posted on 2014-08-20

Clarification: If we get 5 IP addresses from comcast and the first one x.x.x.x is behind one router which has ports for mail server, webserver, etc. pen etc. etc. Can the second one y.y.y.y beind a second router which will have ports open for mail server, webserver, etc. etc. and they will run completely different domains? Is that the idea behind "5" ips?

    Assisted Solution

    All 5 IPs given to you belong to the same subnet meaning they will only have 1 gateway to Comcast.

    You can still achieve your design with just 1 router. You'll just have to configure static NAT and point to the servers you desire

    Can you explain a little more? And does that mean that I have to open "ports" just like I would as I if they were different environments (like different physical spaces)? Will limits be applied here?

    5 IPs means you have recieved 5 IPs from comcasr..out of it one will be comcat gateway..

    now 4 IP is for your use only and you attach to your service ports..all are routed.
