What is a MAC Address?

A MAC address is a hardware identification number that uniquely identifies each device on a network. Unlike IP addresses, which can change based on the network you are connected to, a MAC address is hard-coded into the network interface card (NIC) and remains constant. This unique identifier plays a critical role in network management, allowing devices to communicate with each other seamlessly.

Why is Knowing Your MAC Address Important?

Understanding your MAC address can be crucial for several reasons:

Network Security: By knowing your MAC address, you can restrict access to your network, allowing only specific devices to connect.
Troubleshooting: Many network troubleshooting processes require you to provide your MAC address to tech support.
Device Management: In environments with multiple devices, keeping track of MAC addresses can help manage network traffic and access.
