Static IPs, or static IP addresses, are fixed IP addresses assigned to a computer or device on a network. Unlike dynamic IP addresses (DHCP), which can change over time, static IPs remain constant, providing a reliable and consistent point of access. They offer stability and you may require using them on your network depending on the need.
For systems using Linux Mint, configuring static IPs is simple and can be done with just a few clicks. This example uses the popular Linux Mint Cinnamon Edition.
Click on the Mint menu and choose Advanced Network Configuration from All Applications. It can be accessed from the Preferences menu too.
To edit your wired/Ethernet connection and change it to a static IP configuration, select it and click on the gear icon.
Go to the IPv4 Settings tab and from the drop-down menu, choose Manual.
This will provide a blank entry for the static address to be added. Click the Add button and enter the static IP address, the netmask, and the default gateway.
A cool thing about this network configuration tool is that it can automatically detect invalid IP format and highlight the entry in red while green for valid one.
Click the Save button for these changes to take place. You now have a static IP address configured for your Linux Mint system.
Happy networking.
