ARP Troubleshooting

Address Resolution Protocol (ARP) is a protocol used to map an IP address to a physical machine address, also known as a Media Access Control (MAC) address, on a local network. When a device wants to communicate with another device on the same network, it uses ARP to find the MAC address associated with the destination's IP address. Problems with ARP can lead to communication failures and network connectivity issues, requiring specific tools and techniques for diagnosis and resolution.
