Sure, just make your DNS server authoritive for 195.125.66.in-addr.arpa.
Only problems:

1. You won't be able, unless you can find out how to stay up to
   date with the real data for 195.125.66.in-addr.arpa, to reverse
   resolve the other IP addresses in 66.125.195.x.

2. You and only you, unless you can convince pacbell.net to delegate
   the reverse delegation to you, will be able to reverse resolve it
   into yourdomain.com.

So in other words, it is possible but it's very hard and not worth
the troubles to persuade it.
