Use the captured data to discuss the process in which ARP acquires the MAC address for IP address 10.0.1.12.
What will be an ideal response?
When a host needs to send a request to another host given the IP address, it first checks its ARP
table to see if the corresponding MAC address of the destination host is there. If not, it broadcasts
an ARP request message which contains the source IP and MAC address and the destination IP address. When the destination host processes the request it recognizes that the request refers to itsown IP address. The destination host then generates an ARP reply and transmits the reply directlyto the requesting host. All the other hosts whose IP address does not match with the request ignorethe ARP request.
