Re: AAAA records to be added for root servers

Seems to me that DNS software at the customer level should be able to
respond to the applications immediately from the cache: switch from IPv6
to IPv4 because I have IPv4 info.

The standard behavior would be query with IPv6 the network DNS, and if
they answer with IPv6 info, carry on, if they answer no info return
error, or they answer switch to IPv4 because I have IPv4 info to give you.

Would that simplify the life of IPv6 applications?
