According to Thomas Smith:
> A customer of mine is having issues with their reverse DNS. The 
> situation is this:
> 
> They lease a block of IPs from me. The customer has his own DNS servers 
> (two of them). Forward lookups work fine, but reverse lookups don't work.
> 
> I understand what the problem is--reverse lookups are being directed to 
> my servers since I own the IP block in question.
> 
> The question is: How do I forward reverse DNS lookups for a specific 
> block of IPs to his servers?


See RFC 2317, Classless IN-ADDR.ARPA delegation.
