Well, we can see at ARIN that 206.222.10 >

And that is us, and my question really was why now after 2 years of doing
this way it all of the sudden needs A records for our modem pools? Im not
trying to be argumentative im trying to understand what happened to make the
rules that it runs by suddenly change. Since again, nothing has changed.

Thanks for the input.

Well, I would say that it's rather obvious that this is _some_ kind of
DNS problem. In this case, most likely a mismatch between forward and
reverse DNS. (What a reverse lookup returns should be lookupable and
yield the original IP address. A lot of programs do checks like that.)

Since when you add the offending IPs to /etc/hosts (thus making them
resolve to something) everything works fine, why don't you just add
them to your DNS servers and make sure that is
properly delegated to you?
