ARP command resolves IP addresses to MAC addresses on a local network.
ARP is used to establish communication between devices on the same network segment by mapping IP addresses to MAC addresses.
You would use the ARP command to troubleshoot network connectivity issues, verify ARP table entries, or clear ARP cache.
The “show ARP” command displays the ARP table entries on a network device, showing IP-to-MAC address mappings.
In Linux, the ARP command is used similarly to other operating systems, helping to manage and troubleshoot network connectivity by inspecting and manipulating ARP cache entries.
