Media Access Control Address Solution

Each network adapter has a globally unique physical address burned onto the card by the manufacturer. The physical address uniquely identifies every individual card that connects to the network cable or media. For this reason, the physical address is also call the media access control (Mac address) address.
MAC ADDRESS is six byte long. A typical Mac address might appear like this 00:00:76:54:12:10, where the first three byte is the vendors unique ID and the next three unique identify that card for the vendor. Different manufactures and brands,
places their address in different location, so it require certain command or series of clicks to see your address. I believe this is done for security purpose hence Mac address is implemented in some organizational network to maintain a high level of security profile against attacker from external login interface. In other to achieve this, the network topology will be built on Mac address filtering structure, this will then allow the administrator to manually add and monitor each device Mac address on the network.

Every network switch stores a list of MAC addresses seen at every port and only forward packets to the ports that need to receive the packet, data or information.
Wireless access points often use MAC addresses for access control. They only allow access for known devices (MAC address is unique and identifies devices) with the correct passphrase.
DHCP servers use the MAC address to identify devices and give some devices fixed IP addresses.
Mac addresses are also used as a control measure, to monitor inflow of devices in every network.
