PowerDNS Recursor uses ANY to retrieve both A and AAAA records in one query: http://lwn.net/Articles/275823/ | * Full IPv6 parity. If configured to use IPv6 for outgoing queries | (using query-local-address6=::0 for example), IPv6 and IPv4 addresses | are finally treated 100% identically, instead of 'mostly'. This | feature is implemented using 'ANY' queries to find A and AAAA | addresses in one query, which is a new approach. Treat with caution. I didn't test it enough yet to see any difference in performance or problems with this approach. Hauke
