In this particular instance, its likely that newer smaller ISPs might
have it easier than well established ones who have all sorts of
legacy
gear to worry about.
Indeed, also one question that should be asked is of those who
essentially offer ISP + Infrastructure services, what percentage of
projects are you IPv6 enabling when not specifically requested ?
If those projects whereas IPv6 was not specifically requested were
considered as a value-add to enable IPv6, would those statistics be far
higher ?
Should Comcast be congratulated for even attempting a large scale ipv6
roll-out to learn of the true issues, or chastised for the issues
they've seen. I can see both sides here, large telcos often have enough
in the way of issues to deal with, without making potentially more
headaches.
We all have a part to play in this IMO, from small to large.
