Static IP address not working

Hello

Trying to get an static IP address by editing /etc/network/interfaces isnt working for me. After configuration and reboot the addressing is blank so I had to remove the config to get it back on DHCP.

eth0 is not listed by default in this file for some reason, only the loopback is contemplated in the out of the box config file, is there anywhere else in the OS i should configure this?
