Hmm. Nope - ns4.google.com returns A records only for me.

A colleague suggests it's this:

http://www.google.com/intl/en/ipv6/

You are maybe on a provider who has this enabled?

Does anyone know the details - do the google DNS servers choose to reply 
with AAAA based on AS-path of the querying IP, or netblock? Inbound 
interface?
