host

host

A command-line utility, host performs forward and reverse lookups by querying DNS nameservers, similar to dig.

Here's an example of a forward lookup with host:

$ host www.pearson.com

www.pearson.com has address 195.69.212.200

Here's a reverse lookup with host:

$ host 195.69.212.200
200.212.69.195.in-addr.arpa domain name
pointer www.environment.pearson.com.
200.212.69.195.in-addr.arpa domain name
pointer booktime.pearson.com.
200.212.69.195.in-addr.arpa domain name
pointer environment.pearson.com.
