Look up domains whois/dns using terminal

Terminal is really powerful, I’m often looking up who owns a domain or what IP address a domain has or even it’s A/MX records that are all simple to do with the following commands.

Ping a domain to determine the IP address:

ping dcblog.dev

outputs:

PING dcblog.dev (104.31.82.117): 56 data bytes
64 bytes from 104.31.82.117: icmp_seq=0 ttl=57 time=11.713 ms
64 bytes from 104.31.82.117: icmp_seq=1 ttl=57 time=10.418 ms
64 bytes from 104.31.82.117: icmp_seq=2 ttl=57 time=10.302 ms

Press ctrl + c to stop the ping running.

Look up the whois information for a domain:

whois daveismyname.com

Find what A records a domain has:

host -t A daveismyname.com

Find what MX records a domain has:

host -t MX daveismyname.com
