Configuring DHCP and Static IP on Raspberry Pi Ethernet

In order to configure Ethernet DHCP on Raspberry Pi:

Open /etc/network/interfaces through any text editor:

and modify anything related to iface eth0

iface eth0 inet dhcp

For getting a static IP Address on ethernet:

iface eth0 inet static

address 192.168.1.4

netmask 255.255.255.0

gateway 192.168.1.1

The above changes will assign an ip address of 192.168.1.4 to eth0 interface of Raspberry pi
