It should be created only one base on EUI-64, right? Next I show my interface output Windows XP is RFC 3041 compliant so it generates IPv6 address based on a pseudo casual algorithm. You have two address, one built from mac address based on EUI-64 and one based on that RFC (3041). 2. Why can I not ping to my IPv6 addresses? I can ping to others IPv6 addresses, and the others can ping my addresses. Is this a bug? You can't ping your addresses because you have the Microsoft IPv6 firewall enabled in your system. To disable firewall filtering you must use the folllowing netsh command: netsh firewall set adapter "nome of your interface" filtering=disable. In that way you can ping your IPv6 address. I hope you resolve your problem (in case you can ask me again) Excuse me for my (bad) english. Gabriele Barbagallo -- ------------------------------------------------------------------------ Ing.
