Looking for a DNS contact at AT&T for prserv.net

[Grigor Palandzhyan]

Hi all,

Is anyone here from AT&T, or does anyone have a contact for the team
that runs the authoritative DNS for prserv.net?

We've found a resolution issue with those servers that's affecting
reverse DNS for some of their customers, and we'd like to work through
it with them directly. We tried the SOA contact and haven't heard
back.

Please reach out to me off-list if you can help or point us in the
right direction.

Thanks,
Grigor
