Using Google Public DNS on Ubuntu Server

We prefer Google Public DNS for Ubuntu Server.

Changing  Nameserver

Below are steps to get it/

Open /etc/resolv.conf file and paste following lines in it:

nameserver 8.8.8.8
nameserver 8.8.4.4

Remove/comment out any existing lines. That’s it. 🙂

Testing

ping any domain/hostname. If you get “Failed to resolve host:” error, then there is something wrong in network configuration (apart from DNS).

Note: You can always ping IP address even if your machine do not any have nameserver entries or nameservers are down.
