In Unix, how do I look up IP addresses?

To look up an IP address in Unix, you'll need to know the full name of the computer you're looking up. At the Unix shell prompt, enter one of the following commands:

nslookup machine-name.domain.name host machine-name.domain.name dig machine-name.domain.name

Replace machine-name with the name of the computer you want to look up, and domain.name with the rest of that computer's address.

Note the following:

  • Some newer Unix and Linux distributions do not include the nslookup command, and instead use either host or dig to look up IP addresses.

  • Not all Internet nodes can be resolved into IP addresses by these commands.

At Indiana University, for personal or departmental Linux or Unix systems support, see At IU, how do I get support for Linux or Unix?
