HOW TO ASK QUESTIONS
To ask a question you can use DIG (*nix) or NSLOOKUP (Windows). I prefer DIG and install it on Windows rather easily via GNUWIN.
- -open shell of some kind (putty, command, power, etc)
- -type: dig daknetworks.com
- -type: nslookup daknetworks.com
To ask a question of a specific server:
- -type: dig daknetworks.com @4.2.2.2
- -type: nslookup daknetworks.com 4.2.2.2
To ask a specific type of record:
- -type: dig -t mx daknetworks.com
- -type: nslookup set type=mx daknetworks.com
To ask for an authoritative record:
- -type: dig -t ns daknetworks.com
- -type: nslookup -type=soa daknetworks.com
To ask for all the info:
- -type: nslookup -debug daknetworks.com 1.2.3.4
