Well, you could ping localhost per IPv6... That's chicken/egg - IPv6 never will be widely used if everyone thinks that way. The sense is to break this dependency loop by ecouraging everyone to use it and not to make it easier to completely disable the support. As I said: you -always- have an IPv6 connection to the outside world as long as you have a single official IPv4 address. Not using it because it doesn't fit in your current network is one point, but disabling it in a way to make a future step to IPv6 harder is another. The number of IPv4 only systems is already big enough - we don't need to build new ones. -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
