How to Change MAC Address on Mac, Windows, and Linux
Before we guide you through how to change MAC address, let’s cover a little bit about the basics of MAC for the new users.
What is MAC Address?
The word MAC is a shorter version of “Media Access Control”. The MAC address is also usually denoted as the hardware address or a physical address as they resemble a hardware connector. Every network interface on a computer or a laptop contains a distinctive MAC address. These addresses are individually allocated in the unit; however, you can also alter or take-off the MAC addresses in software. So, it is good to learn how to change the MAC address.
What is the Use of MAC Address?
Besides an IP address, each single hardware unit of the local network has assigned a unique MAC address. But you must be wondering that for what purpose these addresses are made. So, following are the various uses of the MAC address that will make your point clearer:
Fixed IP Assignment
The routers give a fixed IP address to the computers and when any device gets connected, every time it gets a particular IP address if it devises an identical MAC address.
Filtering use of MAC Address
The computer system can also utilize MAC address filtering i.e. it allows only those devices which have explicit MAC addresses for connecting to a network.
Certain ISP (Internet service providers) might need verification with the MAC address and simply permit a device with that particular MAC address for connecting to the Internet
Tracking of Device
Since the MAC addresses are unique, it can be used for tracking purposes also. While using your smartphones, your phone directly scans the available Wi-Fi options that are nearby and transmits its MAC address. This also helps in tracking a particular phone.
