Command:

Explanation:

• sudo: Runs the command with superuser privileges, which is typically required to modify network settings.
• ip addr add: The command used to add an IP address to an interface.
• {desired_ip_address}: The IP address you want to assign to the interface (e.g., 192.168.1.100).
• /{subnet_mask}: The subnet mask in CIDR notation (e.g., /24 for a 255.255.255.0 subnet mask).
• dev {interface_name}: The network interface to which the IP address will be assigned (e.g., eth0, ens33, or wlan0).

Example:

To assign the IP address 192.168.1.100 with a subnet mask of 255.255.255.0 to the interface eth0, you would use the following command:

Result:

This command will configure the network interface eth0 with the IP address 192.168.1.100 and the subnet mask 255.255.255.0 (CIDR /24). The change is applied immediately, but it may not persist after a reboot unless configured in the network settings configuration files.

Additional Notes:

• To verify the new IP address, you can use the command:
  bash

  Копировать код

  ip addr show {interface_name}


  For example:

  bash

  Копировать код

  ip addr show eth0

• To remove the IP address from the interface, use:
  bash

  Копировать код

  sudo ip addr del {desired_ip_address}/{subnet_mask} dev {interface_name}
