[rbldnsd] AAAA Queries?

[David Cary Hart]

A mirror contact me about a large volume of AAAA queries from an ISP.
Can someone offer me a clue how and or why this would occur?

Their log looks like:

10:46:32.002146 IP neutron.blast.net.3649 > mirror.xxx.com.domain: 38739 AAAA? 
228.231.101.81.prc.tqmcube.com. (48)

I cannot figure out what is happening here.

Thanks!
