On a Linux system, IP addresses are automatically assigned by DHCP servers. They are dynamic, and often changing, every time you reboot your system. If the system is a dedicated or virtual server administering remotely, for example, for this it is necessary to have (as a recommendation) a static IP address.
To configure an IP address on a Red Hat system, enter the command
which will list the network connections and devices in the system
$ nmcli dev status
DEVICE TYPE STATE CONNECTION
wlo1 wifi connected Comtrend7FB9
virbr0 bridge connected virbr0
enp3s0 ethernet unavailable --
lo loopback unmanaged --
virbr0-nic tun unmanaged --
Next, you need to change the network interface. To do this, edit the file in the directory /etc/sysconfig/network-scripts
which is an open interface. In a line called“BOOTPROTO=dhcp» needs changes to BOOTPROTO = static».
Also, the IP address itself must be added to this file. For example, this interface will be called IPCONT211
After making changes, run the program systemctl restart NetworkManager to save the changed settings.
