hola, sorry for the confusion, the 192's were just examples nothing to do with my problem. They are stated in the limewire ban hosts section. For a real example i wish to ban ips 9.20.0.0 - 9.20.127.255. But i dont know how to write it specifically other than just every single ip change 9.20.0.1 9.20.0.2 etc... gracias
