Using Lookup With Terminal

The Lookup tool in Network Utility allowed you to identify the IP addresses associated with a domain name and vice versa. In Terminal, the nslookup command effectively replicates this feature.

An example Terminal command on a Mac looks like this:

nslookup apple.com

For a reverse lookup, use the IP address of the domain:

nslookup 17.253.144.10
