Enough talk about viruses and unpatched hosts! <grin> Maybe if we try hard
enough, we can create a Y2K syndrome for the removal of 3ffe:: from global
routing?
----- Forwarded message from Mike Bran <mbran@occaid.org> -----
guess terado services will get a facelift then too? (since they
require/use the 3ffe range for comms)
The most recent draft for teredo only requires use of 3FFE::/16 obliquely:
2.6 Global Teredo IPv6 service prefix
An IPv6 addressing prefix whose value is XXXX:XXXX:/32.
(TBD IANA; experiments use the value 3FFE:831F::/32, taken from a
range of experimental IPv6 prefixes assigned to Microsoft.)
Draft-huitema-v6ops-teredo-05 expired last October, and I can't find it in the I-D tracker. It doesn't seem like it would be too much of a stretch to update that section if a revision was in the works.
In real life, does anybody actually use terado? Are there a well-known set of teredo servers and relays for which some arbitrary, large ISP might measure traffic levels? It seems like if it was enabled it would be possible to measure traffic from teredo's bubbles, even if nobody was actually using it to retrieve content.

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:
http://www.ipv6tf.org/using/connectivity/teredo.php
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).
Regards,
Jordi

In real life, does anybody actually use terado? Are there a well-known
set of teredo servers and relays for which some arbitrary, large ISP
might measure traffic levels? It seems like if it was enabled it would
be possible to measure traffic from teredo's bubbles, even if nobody was
actually using it to retrieve content.
Check http://www.sixxs.net/tools/aiccu/brokers/ which has a list of most
/all (send mail if you know more 
public tunnel brokers and all other
related items.
Only AS31701 (Consulintel) and AS5511 (OpenTransit / Wanadoo France) are
announcing the 3ffe:831f::/32 prefix though.
But from my logs (including ipv6gate.sixxs.net 
I don't see any
traffic coming in from it...
Greets,

Is that 5% of your IPv6 traffic, or 5% of *all* your IPv(4+6) traffic?
Not the above network, but another... I just checked the log of
ipv6gate.sixxs.net (or more precise *.sixxs.org), resulting over the
last day the following 6bone prefixes seem to be active (simple cut
-f1,2 -d: on the address thus first 32bits) these are the only 6bone
prefixes using that service:
4 3ffe:2500
92 3ffe:80ee
110 3ffe:831f
136 3ffe:4019
241 3ffe:80d0
118455 3ffe:321f
507624 3ffe:3201
3ffe::3200::/24 == CERNET
The rest of 6bone is pretty dormant compared to that one.
(Though they might also not be using the service of course)
Then again, check the top 5 6to4 sources (also per /32):
9169 2002:d347
12281 2002:a66f
32554 2002:ca75
65035 2002:de1d
2295865 2002:a269
Take a guess what the last line is from 
In this sample the number for 2001:<something> (RIR space, I didn't
catch anything from non-2001 prefixes) is:
2371150 2001
Other wise put:
