I view complete DNS coverage to be a basic function. All used addresses should have forward and matching reverse records.
But why? It's not like anybody can trust what's in a reverse DNS string, even if it has matching forward. If I'm looking for "ownership", I'm going to registries, not DNS. Since it can't be guaranteed (or even flagged as) maintained, you can't trust any information in that string. -- Chris Adams <cma@cmadams.net>
