There are 249 sites on the 6bone (see
http://www.cs-ipv6.lancs.ac.uk/ipv6/6Bone/Whois/) as of yesterday.

There are also a fair no. of sites not registered directly with the 6bone
registry that are associated with projects like JOIN, G6,  WIDE etc, that
would have to have reverse entries.  This may be another 50 sites (purely
my guess).  So your nos. aren't far off.

As for the large nos. of not responding sites it seems to be the case that
people join up to prove they can do it, do a few simple tests, then go
inactive.  We don't try to discourage this, tho it can be annoying.

I would appreciate seing the list of both sets (those that responded and
those that didn't).


I'm in the process of hardening the 6bone backbone, which mainly consists
of getting agreement from backbone sites (see
http://www.6bone.net/6bone_pTLA_list.html) to self police based on certain
metrics, e.g., routing flaps (merit has some neat reports for us at
http://www.merit.net/mail.archives/html/6bone-routing-report/).  

So I'm always looking for, and at, data such as you just collected.


(As an aside we keep the 6bone operational stuff on the 6bone list, but it
really doesn't matter as I think that most involved folk are on both.}


Thanks,

Bob
