Thank you. 


The large DNS response in IPv6 is a real problem. ATR is one option to adopted in authoritative  server alone. If someone or party have more influence on both resolver and authoritative side (cloud and app provider who can choose their own DNS resolution path),  Mukund’s proposal to fragment the DNS message is a good solution.   https://tools.ietf.org/html/draft-muks-dns-message-fragments-00 


So I do recommend ATR and DNS message fragments should be both considered  in a tool box for large DNS response issues.

   As the increasing use of DNSSEC and IPv6, there are more public
   evidence and concerns on IPv6 fragmentation issues due to larger DNS
   payloads over IPv6.  This memo introduces an simple improvement on
   authoritative server by replying additional truncated response just
   after the normal large response.
