linuxnslookup

nslookup - return only the IP address of host

I'd like to be able to return only the IP from a nslookup command. Currently if I execute:

>nslookup foo21.bar.local

it will return something like:

Server:     11.13.5.134
Address:    11.13.5.134#53

Name:   foo21.bar.local
Address: 11.13.35.312

I would like a command that returns just the:

11.13.35.312

Thanks for any answers.

Solution

  • dig has options to make that easy:

     dig +short foo21.bar.local

    will just give you the A records, one per line (a domain can have more than one A record). To only get the first one:

     dig +short foo21.bar.local | head -n1
