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:
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):
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:
Other wise put:
6to4 2414904 44.61%
RIR 2371150 43.80%
6bone 626662 11.57%
Still an amazing 11.57% of the hits of this traffic sample.
And all coming from the same place too...
Btw, note that 6to4 is only used by 1 very large user site which also
has RIR space and 6bone space. Clearly for them 6to4 is very easy to
use. Btw2 I am not looking at transfered bytes here, but I assume them
to be mostly consistent with the hit count.
Most 6bone prefixes that are still announced are dormant on the net,
they are there but not used at all.
