Depending on how the network is configured, it might assign an IP address to one device and then refuse the connection from the other. Most routers enable administrators to block or allow clients on the network using a feature called MAC address authentication, or MAC address filtering. In enterprise environments, information technology staff enter into the filter the physical addresses of all office workstations allowed to access the network.
This process helps to protect the network and its connected clients by blocking out unauthorized users. When a computer attempts to connect to the network, the router authenticates the device's MAC address. That means the router uses the MAC address to identify the computer; if the address is allowed through the filter, the router then authorizes the computer to establish a connection with the network. Consumers can also use authentication to protect their networks; MAC filtering is especially important if you do banking or access other confidential information from your PC.
