        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.
