How to set static ip on Raspberry Pi

Raspberry Pi uses DHCP to configure its network interfaces by default. The IP address assigned by a DHCP server can change every time you start Pi.

If you want to access the Pi remotely, it should have a static IP address so you know exactly where you want to connect.

This article shows you how to assign a static IP address to the wired network interface port (eth0) of your Raspberry Pi running Raspbian OS.

1. Open a terminal window.

2. Backup the original network interface file :

$ sudo cp -p /etc/network/interfaces /etc/network/interfaces.original

3. Open the interfaces file in a text editor and change the line
iface eth0 inet dhcp
to
iface eth0 inet static.

Add IP address, Netmask and Gateway address just below that line.

$ sudo nano /etc/network/interfaces 
	iface eth0 inet static
	address 192.168.0.11
	netmask 255.255.255.0
	gateway 192.168.0.1

Press CTRL+X to exit. Then press Y to save the file and ENTER to accept the file name

4. Restart networking for the changes to take effect:

$ sudo /etc/init.d/networking stop

$ sudo /etc/init.d/networking start

5. Verify settings:

$ ifconfig
eth0      Link encap:Ethernet  HWaddr b8:27:eb:61:f8:de
          inet addr:192.168.0.11  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:818 errors:0 dropped:2 overruns:0 frame:0
          TX packets:485 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:75805 (74.0 KiB)  TX bytes:52483 (51.2 KiB)
