Blocking these IP addresses will only block users from accessing the main 
napster servers and will not block access to other napster servers, such as, 
opennap, which can be found easily by using the napigator program.  The best 
way to block Napster is to block the ports that the client uses which are 
4444,5555,6666,7777.  Don't quote me on these ports because I can't find my 
documentation at the moment, but I think they are right.
