How to configure Static IP on Raspbian (Raspberry Pi)

It's a common requirement to have a Static IP address assigned to your Raspberry Pi, as it makes life a lot easier to SSH into a box for which you know the IP address, instead of looking around in your router's pages.

This guide is for Raspbian OS for Raspberry Pi, and also tested on B+ model

Log on into Raspbian onto command line and list the network interfaces currently available:
cat /etc/network/interfaces

Note, eth0 is by default configured as dhcp (dynamic ip address)

We will change this behavior to static.

Before we proceed we need to determine the following information. All of these you can easily determine if you have setup your local network (wifi router/switch/hub/etc..), alternatively if your have your Raspberry Pi connected to LAN (eth0) you can run the following commands to get details:
ifconfig

Now note the following values:
inet addr:192.168.2.2
Bcast:192.168.2.255
Mask:255.255.255.0

Next get the Gateway and Destination address (ideally your router IP addess, or use below command):
netstat -nr

Gateway Address – 192.168.2.1
Destination Address – 192.168.2.1

Now, we will edit config and set the static ip details:
sudo nano /etc/network/interfaces


Change the line that reads:
iface eth0 inet dhcp

to

iface eth0 inet static

Next enter the details that you have collected in previous steps:

address 192.168.2.2                Pi's IP address
netmask 255.255.255.0           Mask address
network 192.168.2.1                Destination address
broadcast 192.168.2.255      Broadcast address
gateway 192.168.2.1          Gateway address

Now reboot your Raspberry Pi, and next check the config once again:
sudo reboot

after reboot
ifconfig


That's all folks!
