To enable/disable ARP protocol for the interface, use the on/off options: ip link set dev eth0 arp on To add and remove interfaces: ip a add 192.

To display all interfaces and their details: ip addr show It also shows and modifies the kernel routing tables with the addition/removal of ARP cache entries. It displays network interfaces and configures network devices, just like the ifconfig utility. However, the scope of its functionality covers two layers of TCP/IP protocol, the Data Link layer and the Network layer. Ip is an alternative to the good old ifconfig. On Fedora, CentOS, and other RPM-based distros: yum install net-tools On Ubuntu/Debian: sudo apt- get install net-tools You can resolve the issue by installing the net-tools package using your distribution's package manager. However, this utility is not readily available in Linux distributions, and you may receive an error ' ifconfig: command not found'.

To assign an IP address to an interface: sudo ifconfig eth0 192. You can activate/deactivate any interface by using up/down parameters, as follows: sudo ifconfig up eth0 You can also view all the available interfaces, IP addresses, hardware addresses, and maximum transmission unit size for active interfaces.

It helps you enable or disable a network interface and allows you to assign an IP address and netmask to the selected interface. Network administrators also use it to query and manage interface parameters with the help of configuration scripts. Ifconfig is a command-line utility known for interface configuration in Linux/Unix operating systems.
