Marcello, Might check into getting an IP with BGP (Border Gateway Protocol) or some other IP routing protocol. Not all ISPs offer these services and it is usually offered on a subnet of addresses not a single address. If your providers/contacts can't do this or don't have good answers you might check with www.spectrumnet.us.
