Hi, Paul, You had a very good question - a question I wanted to ask but was afraid I would be considered too careless in IPv6 specs. Seems 'site' in IPv6 is an elastic concept - it all depends on how big your heart is ;-) . But in reality when I tried to learn to configure the 6Bone connection, I was baffled too. Hope you can give us a concise and practical definition very soon. Best regards.
