Disclaimer: Personally I think that the whole notion of reverse IP is ridiculous, especially in IPv6. I proposed that we skip the whole notion in IPv6, possibly providing some alternate, non-DNS, method to get hostname from IPv6 addresses for the rare case where that is useful. However, administrators seem to really like reverse DNS. I don't know why. It's a mystery to me, but they do. Having said all of that, I don't see any strong requirement that this document provide motivation for reverse DNS solutions for IPv6. People ask about the problem, and want solutions, and it would be good to have a document to point them to with some help. Cheers, -- Shane
