5.2.1
A MAC address is unique to every NIC because it is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies. The effect of two different manufactures with the same LAST 24 bits of their MAC address would be nothing. The reason for this is because the first 24 bit would be specific for each individual manufacture and even if the last bits are the same the MAC address will still be different because the first 24 bits are going to be different.

Could not do the arp -s on these computers do to the lack of authority. "The ARP Entry addition failed: The requested operation requires elevation."

Lab Review

1. Dynamic entries are added on a "as needed" basis. The benefit of this is that the dynamic entries left in place are considered
