sudo apt-get install dnsmasq
After installing dnsmasq, the next step is to run the following command to edit the DNS configuration file:
sudo nano /etc/dnsmasq.conf
On the screen displayed, locate the item named 'Add other nameservers here' and replace it with the DNS server address you want to use as shown below:
