[FX.php List] [OFF] Question about RDNS

[Jonathan Schwartz]

Bob,

In this case, the machines are in a colo data center.  I ask them to 
set up the RDNS. No problem there.

The root question is what to request.  As mentioned in the email, I 
have both IP's set up with the SAME domain, and that doesn't seem to 
be the correct way.
