I have a DNS server (pfSense) for my LAN, working perfectly, but some timeouts occur that I can't explain. Especially the "host" command gives the correct answer immediately, but then tries 2 times more with timeouts:
charles3@cluj:~ ยป host -v cluj.int.acme.fr
Trying "cluj.int.acme.fr"
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 14189
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0
;; QUESTION SECTION:
;cluj.int.acme.fr. IN A
;; ANSWER SECTION:
cluj.int.acme.fr. 1 IN A 192.168.1.113
Received 52 bytes from 192.168.1.1#53 in 0 ms
Trying "cluj.int.acme.fr"
;; connection timed out; no servers could be reached
Trying "cluj.int.acme.fr"
;; connection timed out; no servers could be reached
The timeouts happens during last 4 lines of the output. This happens on the two different machines I have (Mac and Linux).
How can I know why are there two trials while answer has already been given?
