This Instructable will show how to quickly configure the Raspberry Pi ethernet port with a static IP address. This makes it much easier to log into it remotely because you will always know what the IP address is of your Pi.
This is a very basic Instructable for PC/Windows users or other not familar with Linux.
This Instructable has been updated (3/3/2017) for the new PIXEL version of Raspian. The network configuration has changed to use the dhcpcd.config file vs the interfaces file.

Step 1: Review Current Network Settings
From the command prompt or LXTerminal:
Type the command "ifconfig"
This command will display the current network settings.
Step 2: Backup the Current Network Configuration
it is a good idea to make a backup of the dhcpdc.conf file if you are new to linux:
sudo cp /etc/dhcpcd.conf /etc/dhcdcp.backup
This will allow you to roll back any changes you make.
Step 3: Modify the Network Settings
To edit the network setting you must edit the dhcpcd.conf file to set up a static IP address.
The following command can be used to load the file into an editor update the file:
sudo nano /etc/dhcpcd.conf
Place these lines at the top of the file too set the Ethernet port (eth0) to a static IP address:
Set the address (ip_address) to the IP address you want the Raspberry Pi to occupy.
Set the routers value to the gateway address
If available, set to domain_name_servers to you name servers
Once the file has been updated, use ctrl x to save and exit.
Step 4: Restart the Raspberry Pi
Once the dhcpcd file has been updated, you must restart the Raspberry Pi for the changes to take effect.
Used to following command to restart:
Step 5: Test the New Network Setup
Use the "ping" command to confirm that the Raspberry Pi is on the network and talking to another computer also on the network.
If you have trouble pinging other computers on the network work, check the following:
1. Confirm that the ethernet cable is firmly connected to the Raspberry Pi and network switch.
2. Confirm that the ip address, mask and gateway are correct.
3. If pinging a Windows machine, sometimes security setting prevent responding to a ping request.
