ANY queries for isc.org and ripe.net are popular (ietf.org has also been seen), since they give a potentially large amplification factor.
FWIW, saw ANY queries at a rate of 10 per second from one IP to a DNS server today, all for isc.org. Saw a few hundred more for tmss.trendmicro.com from a different IP. Other popular names include plus.google.com, maps.google.com, and play.google.com. (all denied by that particular server, which is patched against such). Anyone know if there's a project to track popular amplification names? :-)
