The renumbering is now done...and I never did get to compile a list of all the domains we're lame for.
we had a similar problem when we were switching off the machine formerly known as dns0.britain.eu.net, which seemed to have been a server for most of the UK's DNS at some time, as well as being a resolver for pretty much everyone. Nominet were helpful in providing a list of all domains which in theory it was supposed to be primary or secondary for, but it didn't help where where other delegations were made to it, such as .com and .org, and the .in-addr.arpa was a nightmare! What we did in the end was to use TCPDUMP with a big packet length, dumped it to a file, so that it showed the DNS transactions, and some judicious awk hackery allowed us to see what it was being asked for, what zone transfers worked and who was resolving off it. We managed to stop most of the resolving, and eventually turned off recursion to put an end to that! When the deadline was reached to turn it off, we'd gotten the number of zones down from many hundreds to perhaps a couple - just the ones where the TLD delegations were untraceable or hopelessly broken.
