DNS troubles with Ubuntu Server 12.04

Some customers have been having DNS issues after setting a static IP on Ubuntu 12.04.1 where the server is no longer picking up the DNS settings as it was before; this can be easily fixed by adding the following to /etc/network/interfaces after the eth0 entry:  
dns-nameservers [ip.of.your.router]
  e.g., for a modem/router that’s 10.1.1.1 on your local network, your /etc/network/interfaces file might look like:  
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 10.1.1.50 netmask 255.255.255.0 gateway 10.1.1.1 broadcast 10.1.1.255 dns-nameservers 10.1.1.1
Restart your network with:  
sudo /etc/init.d/networking restart  
…then try pinging Google or something similar and you should have success 🙂   It’s generally not advisable for Australians to use nameservers located elsewhere, e.g. Google’s public DNS’ 8.8.8.8 or 8.8.4.4 – some things which are unmetered by your ISP may be metered if you do so.
