• Reverse ARP

  • RARP stands for Reverse Address Resolution Protocol. It's a networking protocol used to map a hardware address (such as a MAC address) to an IP address.
• RARP Process

  1. Request: A host that needs to discover its IP address sends a broadcast RARP request packet onto the network. This packet contains only the MAC address of the sender and a request for its IP address.
  2. Server Response: A RARP server, typically present in the local network, receives the broadcast request. The server looks up the MAC address in its table to find the corresponding IP address.
  3. Reply: The RARP server sends a unicast RARP response packet back to the requesting host, containing the IP address mapped to the MAC address.
