dig is a tool for troubleshooting DNS issues. It is very similar but preferred to the now obsolete nslookup. dig is included with the BIND DNS software, which is part of the base system.
The command format is
dig [@server.you.want.to.query] [RECORDTYPE] record_you're_looking_for
for example:
dig @192.168.1.1 A freebsdwiki.net
will query the DNS server running at 192.168.1.1 for the "A" (host) record for freebsdwiki.net. You should get results very much like:
; <<>> DiG 9.2.3 <<>> @192.168.1.1 freebsdwiki.net a ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 2879 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;freebsdwiki.net.
