Why is the destination hardware address all 0s in the ARP request message?
3.
Why would the destination hardware address of the frame be a broadcast address?
4.
When initially establishing contact with the Dynamic Host Control Protocol (DHCP) to acquire an IP
address, a host will transmit an IP packet saying “Give me an address.” If you examined the header of the IP
packet, what would be the source IP address and the destination IP address?
5 . Combine the following three blocks of addresses into a single block
( Show your work using binary bits) :
• 16.27.24.0/26
• 16.27.24.64/26
16.27.24.128/25
