Just now my NS queries for the lists used in SpamAssassin:
sa-trusted.bondedsender.org
sa-accredit.habeas.com
bl.score.senderscore.com
are all returning SERVFAIL so I can't tell if they even have any
nameservers on IPv6. Obviously if all their nameservers are on IPv4
then they are never going to see queries from IPv6 resolvers and it may
be of questionable value collecting those IPv6 addresses, but even then
it seems a bit short sighted.
It seems they don't like you asking for the NS of those domains directly
but they will provide it if you ask for an A or TXT of a child. And
indeed they do not seem to support queries via IPv6 -- the queries for a
test address all succeed when made via IPv4 but all fail when made via
IPv6 (e.g., using -4 vs -6 with dig +trace 2.0.0.127.$dnsbl) so it does
make some sense that you cannot register to query them that way. Alas
lots of companies are short-sighted, or very slow to evolve.
