Hello Guys:

This is more of a personal problem. I work for a University and the Univ has given me an ip address range 135.123.39.2 - 135.123.39.254 for my lab. Every time I bring a computer for the lab, I have to ask the university to add the dns name to the dns server. Recently we have split up within the lab and we are having trouble coexisting. So we want to separate. Now the whole setup is like this

rouetr -> firewall -> switch -> workstations/servers

There is only one port coming out of the the router and going to the my linux firewall (bridge mode) and then to the switch where i distribute all the IP tot he rest of my machine. Now I am trying to understand the University setup. This is a Class B address (135.123.39). But if I wanted to separate within or ask the univ to separate,

1) How they would do it and

2) How can I do it ?

I want to know all my options. I would be glad to provide you with more info if needed

Thanks
