Hi , I have data as follows
a.rameshops5446.com. 86400 IN A 1.2.3.1 a.rameshops5446.com. 86400 IN MX 10 a.rameshops5446.com. I queried domain "a.rameshops5446.com" with type ANY against bind9.6 . Actual Result: Bind is returning above two records in answer section and also returning A record in additional section as follows. # dig @localhost a.rameshops5446.com. any ; <<>> DiG 9.6.1-P3 <<>> @localhost a.rameshops5446.com. any ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 33411 ;; flags: qr aa rd; QUERY: 1, ANSWER: 2, AUTHORITY: 2, ADDITIONAL: 1 ;; WARNING: recursion requested but not available ;; QUESTION SECTION: ;a.rameshops5446.com.

I know if MX pointed record have any A/AAAA records will return in additional section. but in above case already the same A record returned in answer section. Is bind result correct? could you please clarify me. Thanks & Regards, Ramesh
