Its not a question of stopping returning an A RR.
Its a question of when they'll start to return AAAA RRs, when queried for one.
Especially when the AAAA query is within an IPv6 packet.
The answer is June 6th this year - http://www.worldipv6launch.org/

Dual-stack hosts query for a AAAA record first, and then fall back to querying for an
A record if they don't get a reply. The trick is to make sure they don't receive a
query for an A RR in the first place, because if they do - the customers ISP has failed.

Its not Facebook and Yahoo that have failed here - its Bigpond, Optusnet, and all the
other ISPs that aren't yet handing out IPv6 addresses in their DHCP responses.

Mark - this is all wrong. Nobody has to stop listening or carrying IPv4. They just
have to start listening to and carrying IPv6 as well.
