Looking at the most recent IPv6 data available at CAIDA you can see the =
customer cone size:
http://as-rank.caida.org/?data-selected-id=3D15
Be careful as the tool seems fragile when switching from the 2014-09-01 =
IPv6 dataset and trying to sort by options, it seems to switch back to =
IPv4 silently.
Prefixes and/or AS=E2=80=99es in customer cone are likely the best =
measure, but even there Cogent is 2x HE.net. The only place where =
he.net leads is the transit degree with is likely distorted because of =
what you mention above, full tables, etc.
I find this data interesting and wish there was something more recent =
than 2014-09-01 to test with. Perhaps I could do something with all =
these atlas credits I have. (or someone could use them for me).
