With various network tools, hackers can see your MAC address. Whenever you go offline, hackers will take the opportunity to “borrow” your MAC address and do various illegal activities. If you use the same MAC address for an extended period of time, it will be easy for hackers to impersonate you. Many cyber criminals constantly change their MAC address when carrying out their acts. However, MAC address spoofing is an illegal activity in many countries.

If you regularly change the address assigned to your network adapter, it will be harder for hackers to track your movement. Using the same MAC addresses could pose a potential security risk. When it comes to maintaining your network, security factor often comes into play. For network administrators, changing MAC address is one of the most effective tools in their arsenal.

The IP address of your server travels far through the Internet and everyone or every device knows it widely. IP address works differently and it is assigned to each device on the local network and the Internet. Remember IP and MAC addresses are different. Similarly, your network adapter only knows the MAC address of adjacent network adapter. Only the adjacent network adapter knows the MAC address of your network adapter. However, MAC addresses don’t travel very far. The network adapter of your computer is identified by its MAC address. This addressing system is essential for directing data packets from one network adapter to another. No two network adapters can have identical MAC address. Machine Access Control or MAC address is a serial number system for network adapters.
