How to configure network interface in Ubuntu

It is likely that the computers in a network use dhcp to get ip addresses, that means these ip addresses will change frequently if you move the computer to another interface of the router or switch (which is exactly what I am facing right now), I want to configure my computer to use static ip address, the easiest way to do this is modify the configure file in /etc/network/interfaces, following these steps:
1.Use ifconfig to figure out which interface you are currently using (eth0/1); 2.Use ip route show to find the default gateway (the first line starting with default); 3.Sudo gedit /etc/network/interfaces:
Add the following information to that file:

iface eth0 inet static
address 172.31.8.22
gateway 192.31.8.1
netmask 255.255.255.0
dns-nameservers 202.202.0.33 8.8.8.8 8.8.4.4

4.Restart networking services:
sudo service network-manager restart
sudo service networking restart
sudo service resolvconf restart
