I thought we all would have learned the lessons from IPv4 days, but it
seems some will just never learn.

BTW, and this is NOT directed soley at Erik, but EVERYONE in this
thread, this morning I see my inbox flooded with messages, ummmmm, we
are all on the SAME mailing list, I, like most of you, don't need two
copies...  seems IPv6  also means we have to learn others all over again
on how to respond to mailing list messages, and not CC every person who
ends up in the thread  *sigh*
I assume we have all been around long enough to know better :)
