A quick primer on dig
Dig is a DNS lookup utility developed by BIND which helps a lot while troubleshooting DNS issues (which are more common than you probably think #hugops). I use
digfairly often and thought to write an introductory guide on how you can use
digwith some practical examples that’ll help you
digthrough DNS issues faster (sorry for the lame pun, couldn’t resist.)
