You need to give the customer control of the reverse-lookups which associate IPs with hostnames, rather than the other way around. If you are trying to do this on a non-classful boundary, see: http://www.menandmice.com/ONLINE%20DOCS%20AND%20FAQ/Glossary/Classless.Deleg ation.htm If you choose not to delegate non-classful reverses, you will have to make the entries in your own server - much wiser to delegate, I think.
This has worked very well for us. I would also strongly recommend the O'Reilly "DNS and BIND" book by Cricket Liu - if you are an ISP, you need to know DNS cold. Of course, if you are using MS for DNS, all bets are off! Reverse DNS is an important tool for discovering the identity of a host - often used to check interesting log entries. Also, for certain export-controlled software, sites will compare forward and reverse DNS entries before allowing the download to proceed.
