Setting a Static IP Address

Before you set a static IP address, obtain the name of your Ethernet link by running the following command:

networkctl
IDX LINK             TYPE               OPERATIONAL SETUP
  1 lo               loopback           carrier     unmanaged
  2 eth0             ether              routable    configured

In the results of the command, you can see the name of an Ethernet link, eth0.

To create a network configuration file that systemd-networkd uses to establish a static IP address for the eth0 network interface, execute the following command as root:

cat > /etc/systemd/network/10-static-en.network << "EOF"

[Match]
Name=eth0

[Network]
Address=198.51.0.2/24
Gateway=198.51.0.1
EOF

Change the new file's mode bits by running the chmod command:

chmod 644 10-static-en.network

Apply the configuration by running the following command:

systemctl restart systemd-networkd
