This can make you completely anonymous on a public network, hence, protecting you from cyberattacks on a public network. Changing the MAC address makes the network devices treat you like a new individual. There may be numerous reasons why you want to change the MAC address on your Linux computer. Why You May Want to Change the MAC Address? Unlike an IP Address, which can be changed permanently, the MAC address gets reverted to the original manufacturer’s address when you reboot the device.
However, we can change the MAC address using some neat software tricks, which we will learn in this article. Moreover, the IP address gets assigned by the Internet Service Provider(ISP), and the MAC address is assigned by the manufacturer, as we mentioned above. That means an IP address makes it easier to locate your device, so the network knows where to send your data. While the former is used to uniquely identify devices on a network, the latter helps identify a device’s connection to the network.
So it usually cannot be changed, or at least they don’t change on their own like an IP address.ĭifference Between MAC Address and IP AddressĮach network device needs at least two addresses to get recognized by other devices and network interfaces – one is the MAC address, and the other is the IP address (Internet Protocol address). That’s because the MAC address is assigned by the manufacturer and is burned into the device’s hardware. It is also referred to as the Physical address or Burned-in address. The MAC address is a 48-bit hexadecimal address consisting of six sets of two digits or characters separated by colons or hyphens.
This address is used to identify and communicate with other devices, be it a computer, smartphone, or printer, on a network. As mentioned above, the MAC Address (or Media Access Control address) is a unique identifier used to recognize devices connected to a network.
