What is dig ?

We use the dig (domain information groper) command to query Domain Name System (DNS) name servers.

When we pass a domain name to the dig command, by default, it displays the A record (the ip-address of the site that is queried) as shown below:

Gurudattas-MBP:~ gnadig$ dig google.com

; <<>> DiG 9.8.3-P1 <<>> google.com
