How To Configure Static IP On redhat?

Setting a static IP on Red Hat ensures your system always uses the same network address, which is important for servers or devices requiring consistent connectivity.

Step 1: Identify Your Network Interface

List all network interfaces to find the one you want to configure:

nmcli device status

Look for interfaces like ens33, eth0, or similar.

Step 2: Configure the Static IP

Replace ens33 with your interface name, and set the IP, subnet, gateway, and DNS:

sudo nmcli con mod ens33 ipv4.addresses 192.168.1.200/24
sudo nmcli con mod ens33 ipv4.gateway 192.168.1.1
sudo nmcli con mod ens33 ipv4.dns "8.8.8.8 8.8.4.4"
sudo nmcli con mod ens33 ipv4.method manual

This switches the interface from DHCP to a static IP.

Step 3: Restart the Network Connection

Apply the new configuration by restarting the interface:

sudo nmcli con down ens33
sudo nmcli con up ens33

Step 4: Verify the Static IP

Check that the static IP is active:

ip a

You should see 192.168.1.200 (or your assigned IP) associated with the interface. Your Red Hat system now has a static IP configured and ready for consistent network access.
