Re: [OCCAID] 6bone addresses going away in June

  • Date: Fri Jan 06 12:58:59 2006

Ho Joe, all,

The last I heard was that the draft was pending of the final step with the
IESG review or something similar, but I'm not completely sure. Then IANA
will assign a production prefix.

I'm aware of at least 8 Teredo Relays (some of them only available within
specific ASs). We run one of them, and yes, have some traffic there, so
there are real users. I know at least about 2 *big* carriers which recently
also have setup Teredo Servers+Relays, and some more being setup. Some of
them are listed at:

Teredo is being used automatically by several applications. Some of you may
haven't noticed about it, but if you are XP SP2 user its there and working
some time, even if you don't enable IPv6 (Teredo gets enable by some peer to
peer apps).
