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.
