comcast ipv6 PTR

Wed Oct 9 21:07:12 UTC 2013

The below is largely accurate.  Comcast will support the creation of IPv6
PTR for static commercial IPv6 customers when we launch the same.  We are
currently in trial for dynamic commercial and are expanding our dynamic
trials.  Static IPv6 trials will be starting soon, hopefully November.

I believe business customers (with a static assignment) can request
reverse DNS entries.  Residential customers are not guaranteed a static
assignment, so they can't get reverse set.
