Devices with these addresses are not reachable globally and are accessible within the LAN only. Internal IP addresses are for messaging and connectivity within the internal network.
IPv6 addresses support a much larger range and are formatted like y:y:y:y:y:y:y:y where each y is a segment that can range between 0 and FFFF in hexadecimal like 2001:0db8:0001:0000:0000:0ab9:C0A8:0102.Īn IP address helps in location addressing of the connected device and for network interface identification.Īlso, we need to remember that each connected device can have two types of IP addresses: The address of each device in an IP subnet (a kind of subset of complete IP range) should always be unique means no two devices on the same subnet can have the same IP address, otherwise, it will cause an IP address conflict.įor IPv4, its format can be 4 octets like x.x.x.x where each octet is 8 bits or 0 to 255 in decimal. One of the most common and popular examples of a network built on IP addresses is World Wide Web and Internet. In the output, you will receive the ARP reply from the destination system containing its MAC address.An IP (Internal Protocol) address is a unique identifier that identifies a device on the internet-connected to the TCP/IP protocol and enabled communication over it. If your system has multiple NICs, you can specify from which interface a request should be sent using the -I flag (capital "i") followed by the interface name: sudo arping -c 1 -I interface_name įor instance, the following command will send one ARP request from its ens33 interface to the remote system's IP address 192.168.42.133.
Once installed, find the MAC address of another system on a network by specifying its IP address as an argument using the following command: sudo arping -c 1 On RHEL-based distributions: sudo yum install arping On Debian-based distributions: sudo apt install arping You can install arping using the following commands: It is different from the ping utility which functions at the third layer. It functions at the second layer in the OSI model and sends the ARP request to the system to determine whether it is alive and responding. The arping utility helps you discover and probe local systems on a network.
