How does the ARP process use an IPv4 address?

  • to determine the MAC address of the remote destination host
  • to determine the MAC address of a device on the same network
  • to determine the amount of time a packet takes when traveling from source to destination
  • to determine the network number based on the number of bits in the IP address

Explanation: The ARP process is used to complete the necessary mapping of IP and MAC addresses that are stored in the ARP table that is maintained by each node on a LAN. When the destination device is not on the same network as the source device, the MAC address of the Layer 3 device on the the source network is discovered and added to the ARP table of the source node.
