However, I've noticed also that Comcast hasn't bothered to give PTR to their routers, either.I have a Comcast residential circuit with IPv6, and I see reverse DNS for router hops past the first device. --
CenturyLink offers 6rd to both residential customers and business, but no way to set RDNS on the individual /64 or /48s assigned to each static ipv4 address the customer has. Rather huge omission, IMHO. I got bit by this bad when !$@& google started outright rejecting email from ipv6 addresses with no RDNS. Yay exim for allowing me to tag broken remote smtp servers to only use ipv4. Brielle
