The approach I perfer is to block only IP addresses that are stated in the 
provider's TOS/AUP as not allowed to  run private servers.  AOL, Cox, 
PacBell, and many others fall in this area.  The user agreed to it when they 
signed up, I see no valid reason not to enforce what the provider in 
question has stated as policy.

If the provider allows it in their TOS/AUP, the there is no justification to 
treat it as dynamic.

I am not going to speak for other methods, my method is to enforce what a 
provider devlares as dynamic and investigate questionable ones.
