[other references to 2001:: addressing snipped] I hope I am not being toooo picky here, and I realize this is not part of your main point... If your reference to 2001:: addressing simply means "non-tunneled, globally routable IPv6 addressing," then I suppose it is okay. But please note that there is now a lot of native (non-tunneled), globally routable IPv6 addressing that is outside of 2001::/16. ARIN, for example, is allocating blocks out of 2607::/16 and there are quite a large number of prefixes elsewhere in the designated globally-routable 2000::/3 that are *not* 6to4 addresses. The reason I bring this up is that I have already seen certain applications, such as one for registering AAAA records for DNS servers in a certain TLD, that don't allow anything other than 2001::/16. (Fortunately that application was fixed quickly when those responsible were notified.) Just making sure others aren't careening toward making the same mistake. michael
