We have a policy which restricts students from hosting servers in the residence halls. 
Students with dynamic IP client software can easily circumvent hardware based (acl) 
restrictions/enforcement of this policy. (i.e only allowing "tcp established" connections 
inbound on an interface)

They shouldn't.
I'm not concerned about the ISP's AUP. It's the campus student policy which forbids 
students from becoming web, FTP, email servers or "whatever" servers.

We shouldn't.

We are not doing this.

I have not seen anywhere in our AUP, verbage prohibiting campus users from 
registering their IP address with other nameservers. But this an excellent point, and 
one that I'll suggest we adopt. In the meantime, and back to the original question ---
what are other universities doing to manage the proliferation of students running 
Dynamic IP clients which allow them to register their (dynamic) ip's with other 
nameservers? i.e., are there known dynamic IP client ports which can be thrown into 
an acl? etc.
