From a purely network operations perspective: YES, every IP address should have matching forward & reverse DNS. That's been beyond best practices and into the "everybody does it unless they're really stupid" realm for well over a decade. Reverse DNS has only become /more/ important as spam-blocking efforts noticed the strong correlation between networks too lazy to maintain reverse DNS, and networks too lazy or evil to care if they were hosting spammers. As for the finances...that's up to you, but I've never before heard of a provider who charged extra for it. -- J.D. Falk okay, what's next? <[email protected]>
