2 dynamic ips-separate with router/switches

I have two dynamic ips from Comcast. One computer is connected directly to the switch-for my son's games. He has two computers in his room with separate ips. The other computers in the house are connected to the router. The cable modem is connected to the switch. I have been able to use separate ips this way. One for my son and the other IP off of the router for several other computers in the house. However, the router only has 4 ports. I want to add more computers to the router side. I want to leave my son's separate ip connected to the switch. HELP!

Just add another switch to the router.  If you add a four port switch, you will have a total of 6 available ports.

I assume you have separated these networks for security as well, if so, maintain your existing configuration and add another switch with as many ports as you feel you will need. You could even install another router between your sons computer and the existing switch to give him additional security and more ports for him.
