How do I install dig (the DNS lookup tool)? I can't figure out what the package name is.

    Strange that you don't have it. Package ubuntu-standard directly depends on dnsutils which contains dig, nslookup and nsupdate utilities. Is your system ok? Can you try sudo apt-get install ubuntu-standard? – ulidtko Feb 7 '11 at 2:39

  • ubuntu servers often do not come with dig – Scott Stensland Dec 1 '16 at 22:04

You can install it by opening a terminal and typing

sudo apt-get install dnsutils

Or via the Ubuntu Software Center by clicking bellow:

Install via the software center

For future reference, I found this out by doing a quick search with apt-cache:

apt-cache search dns dig

And then verified with aptitude.

  • A much more easier command to determine the package, provided you know complete path of file you are searching is $ sudo dpkg -S /usr/bin/dig dnsutils: /usr/bin/dig – Jamess Feb 7 '11 at 4:53

    @James, this command will only work if you had dig already installed, while Oli's will search all available packages. – Javier Rivera Feb 7 '11 at 8:20

    @Jamess You can search by filename on packages.ubuntu.com. And FWIW, you don't need sudo to run dpkg -S. – Iain Lane Feb 7 '11 at 9:58
sudo apt-get install dnsutils

To find out which package a file is in you can do

sudo apt-cache search dig

Sometimes that works, but in this case it was useless. You can search for which package a specific file is in using the 'Search the contents of packages' search form here:


  • As @oli said in their answer, adding keywords can make apt-cache search more useful; in this case the combination of dns and dig keywords returned a much smaller list (about a dozen packages) than either by itself (hundreds for dns, almost a thousand for dig). – Mark Reed Jun 19 '17 at 14:38

Another command:

apt-file search /usr/bin/dig

You should install apt-file and update it beforehand:

sudo apt-get install apt-file
sudo apt-file update
