[dns-operations] IPv6 & IPv4 addresses

 In your previous mail you wrote:

   I see from another thread some resolvers are using ANY to do a single 
   query to get both A & AAAA addresses. This may be fine generally,

=> it is unfair: you are taking advantage of the time zone: people

 To be serious it is a bad bad bad idea. If you don't want to wait A
(or AAAA) query to fail before trying AAAA (or A) then just send both
queries in parallel.
