Why would an administrator need to know the IP and MAC addresses for a given computer?
What will be an ideal response?
Larger networks are managed virtually and filter out all packets from computers that are not registered by MAC addresses. A network administrator must know the MAC address for each machine in order to correctly administer the network and keep outside machines off internal systems. Knowing which MAC address has a given IP address can help manage a network. An administrator will know which machines are sending/receiving what information. Knowing both MAC and IP addresses are critical parts of diagnosing network problems.
