[GLLUG] Finding IP ranges (similar to dig)??

[Benjamin Cathey]

Is there a tool to allow you to find ALL variations of IPs for a certain domain?  For instance, lcc.edu, angel.lcc.edu and starport.lcc.edu - all different IPs.  Is there a way (online or with a tool) to get all variations on the www that they use and all the IPs associated with it?  

The reason I ask I have a locked down public terminal (using the a firewall box (running smoothwall 2.0) and I need to open it up so people can check their grades, etc.  I know of those 3 ips but there MUST be others as well.

Thanks,
