Whether you’re using WiFi or Ethernet, every device on your network needs a unique digital “name tag” so the routers and switches know exactly where to send the data. This is where a MAC address (Media Access Control) address comes into play.
A MAC address is like a device’s fingerprint: no two are exactly alike, and it helps your network know who’s who. In this guide, we’ll break down what a MAC address is, why it matters, and how you can find it on your devices.

In this guide, we explore what a MAC address is, the types of MAC addresses, its significance in networking, and how you can locate it on your devices. Unlike the IP address or software address, the MAC address can’t be configured or managed**. When you purchase any new device with networking capability or a computer with a Network Interface Card (NIC), it comes with a pre-configured with its own MAC address.
A MAC address is a unique identifier assigned to network interfaces for communications. It’s like a digital fingerprint for your network devices and is essential for network protocols to efficiently route data.
A MAC address is a key component of media access control for Ethernet and WiFi connections, with key characteristics:
MAC addresses play a crucial role in wired and wireless network communication. All your devices have a unique wireless MAC address or MAC Ethernet address for local network connections, used in the following ways.
Every device connected to your home network has a unique MAC address. If your computer has multiple network adapters (for example, an Ethernet adapter and a wireless adapter), each adapter has its own MAC address. Sometimes you need to find the MAC address of something attached to your network, such as an IoT device. An easy way to find a MAC address is to log in to your router and then visit the attached devices page to see the MAC of a device that is connecting.
While the specific steps can vary depending on the device and operating system, there are general guidelines for finding your MAC address.
Some earlier Windows Systems: Under Ethernet adapter Wireless Network Connection, a Physical Address displays. This is your computer’s Ethernet MAC address.
*If you do not see your operating system listed, refer to your device’s user manual, product support website, or network administrator.
By understanding and being able to locate your media access control address (MAC address), you gain deeper insight into the workings of your network settings and devices. This knowledge is crucial for advanced network system settings management, security, and troubleshooting.
We hope this guide has helped demystify MAC addresses and shown just how essential they are to keeping your network running smoothly. Understanding your MAC address is like having the keys to the backend of your home network—once you know where to find it and what it does, you can manage security, troubleshoot devices, and fine-tune your network with confidence.
