Change Ubuntu machine search domain

 For ubuntu 16.04, add the following to file /etc/resolvconf/resolv.conf.d/base

search xxxxx

where xxxxx is the search domain to be added to resolv.conf.

After make that change, you will need to restart the networking services.

systemctl restart networking


The following procedure does not work for ubuntu 16.04.
You will need to edit this file with your favorite editor:

sudo nano /etc/dhcp/dhclient.conf

Once in file, you should see a commented line with the word supersede next to it:

#supersede domain-name "...."

Uncomment that line, substitute the name supersede for append, then add the domain names you wish to search (follow the example below and leave a space after the first "):

append domain-name " ubuntu.com ubuntu.net test.ubunut.com";

If you just want to use complete different search domain, then just leave the

word supersede, only replace the domain names.

supersede domain-name " fabric.com whatever.io"
