Static Network setup

If you wish to disable automatic configuration for an interface and instead configure it statically, add the details to /etc/dhcpcd.conf.

For example:
vi /etc/dhcpcd.conf

Add these lines to the bottom of the file
interface eth0 static ip_address=192.168.0.4/24 static routers=192.168.5.1 static domain_name_servers=192.168.5.1 8.8.8.8 # OR # gnl20200324 static IP configuration: interface eth0 static ip_address=192.168.5.84/24 #static ip6_address=fd51:42f8:caae:d92e::ff/64 static routers=192.168.5.2 static domain_name_servers=192.168.5.1 8.8.8.8 fd51:42f8:caae:d92e::1 # cat /etc/resolv.conf

You can find the names of the interfaces present on your system using the ip link command.

NOTE:
Previous versions of Raspbian used the file /etc/network/interfaces for network interface configuration.
If an interface is listed in this file, any settings there will take precedence over what is in /etc/dhcpcd.conf.
