What is my MAC address?
MAC (Media Access Control) address is just an identification number of network adapters. A network adapter is a device through which you can connect your PC with other devices or networks. Examples of network devices are Ethernet, WiFi, and Bluetooth.
Your PC or Laptop must have these adapters. Every device has a particular number that is called a physical address. This physical address is called a MAC address. See more details from Wikipedia.
A PC, Smartphone, and anything that connects to a network will have a unique identification number known as MAC (Media Access Control) address. It is also the hardware address of the Network Interface Card (NIC) of the PC. A MAC address is assigned by manufacturers and embedded into the device’s network interface card and it’s permanently tied to the device (like Ethernet, Wi-Fi, and Bluetooth), which means that a MAC address cannot be changed.
When your device detects a router, it sends out its MAC address to initiate a connection. This is where the IP address comes in and your router will assign you an IP address so that you can connect to the local network. MAC addresses are permanently burned into your device while IP addresses can change depending on your location. In simple words, MAC address is used in the local network whereas the IP address is used to identify network devices all around the world.
The MAC address consists of 6 pairs of digits and characters that might or might not be separated by hyphens 05-A8-34-C3-67-B4 or 05A834C367B4. Generally, we don’t need such information but sometimes we might need a MAC address to identify a device or configure networking permissions on a router. Or there’s a chance you’ll need to know your PC’s MAC address to diagnose or resolve some computer network errors.
When do I need MAC address?
