How to permanently set static IP in Ubuntu

Edit the file:

 /etc/network/interfaces 

Edit the section for your primary network interface. It is probably device eth0 or eth1. Say you are on a 192.168.1.0 network and you want to set your static IP to 192.168.1.66. These values are typical.

 auto eth0
 iface eth0 inet static
     address 192.168.1.66
     network 192.168.1.0
     netmask 255.255.255.0
     gateway 192.168.1.1
     broadcast 192.168.1.255
