I can only first suggest starting to use 'dig', as then it also shows 
you which is the server that is answering you and it is using TCP or 
not, just in case a random one is chosen from some config snippet.

Note that upstream servers, NAT/firewall/router boxes can interfere with 
DNS and cause weird/unknown results too.
