Your MAC address is a unique identifier assigned to your network interface card (NIC). Think of it as your device's physical address on a network. It's a hexadecimal number, usually displayed with colons or hyphens separating groups of two digits. This address is crucial for your device to communicate on a network.
Finding Your MAC Address:
The method for finding your MAC address varies slightly depending on your operating system and device. Here are some common methods:
On macOS:
- Open the Apple menu.
- Click System Preferences > Network.
- Select your network connection (Wi-Fi or Ethernet) and click Advanced.
- You will find the MAC address on the Hardware tab. (This is confirmed by multiple sources, including the University of Alabama's guide and other guides referenced).
On Windows:
- Click the Start menu.
- Type
cmdinto the search bar and open Command Prompt. (As noted by Florida State University's service center). - Type
ipconfig /alland press Enter. - Look for the "Physical Address" listed under your network adapter.
On Mobile Devices (iOS and Android):
The location of your MAC address on mobile devices varies by device and operating system version, but it's usually found within the device's network settings or "About" section. Consult your device's manual or online resources for specifics. For example, on an iPhone, you might find it in Settings > General > About > Wi-Fi Address. (as mentioned in the Apple Community discussions)
