i'm not sure whether appropriate place add - (possible) cause have seen not mentioned above request aaaa record (ipv6 address) being responded record (ipv4 address).

dns debug logging (windows 2008 r2 sp1) captured requests 192.225.156.200 , corresponding responses. in each case response followed in debug log event “the dns server encountered invalid domain name in packet 192.225.156.200. packet rejected. event data contains dns packet.”

the domain name in response same in query, , looks ok.

the logged query shows aaaa record (ipv6 address) request , logged response returned record (ipv4 address).

http://www.rfc-editor.org/rfc/rfc4074.txt “common misbehavior against dns queries ipv6 addresses” says, under “expected behavior”:

   suppose authoritative server has rr has no aaaa rr

   host name.  then, server should return response a

   query aaaa rr of name response code (rcode) being

   0 (indicating no error) , empty answer section (see

   sections 4.3.2 , 6.2.4 of [1]).  such response indicates that

   there @ least 1 rr of different type aaaa the

   queried name, , stub resolver can rrs.
