In the world of networking, each device is assigned a unique identifier that allows equipment to find each other and exchange data. This identifier is called MAC address (Media Access Control Address). It's factory-programmed into your network card or Wi-Fi module and serves as a kind of digital fingerprint for your device. Knowing where to find this code is essential not only for system administrators but also for regular users setting up a home network.
Why would you need to find this value? Most often, it's used to set up access filtering on a router, allowing connections only to specific devices. This knowledge is also useful when diagnosing network problems or cloning MAC addresses for providers that restrict access to specific equipment. In this article, we'll cover all the current methods for obtaining this information on various operating systems.
It is important to note that in modern operating systems such as Windows 10, iOS And AndroidMAC address randomization has been implemented to protect privacy. This means the device can use a temporary, random address when scanning networks, hiding its real physical identity. Therefore, when configuring the router, it may be necessary to disable this feature or look for the "real" address in the deep system settings, rather than the one displayed in the connection status.
Using the Command Prompt in Windows
The fastest and most reliable way to find out physical address In the Windows operating system, this is done using the built-in command line utility. This method is universal and works on all OS versions, from Windows 7 to the latest Windows 11You don't need to be a programmer; you just need to copy one short command.
To begin, open the Start menu and type the word in the search bar. cmd or Command line and press Enter. In the black window that opens, enter the command ipconfig /all and press Enter. The system will display a huge list of parameters for all network interfaces. You need to find the section corresponding to your wireless adapter (usually it's called "Wireless Network" or contains the word Wi-Fi).
⚠️ Important: If you see multiple lines of MAC addresses, be careful not to confuse them. Look for the one that corresponds to the wireless module. The address for the Ethernet controller (wired network) or Bluetooth adapter will be different.
In the list of parameters, find the line "Physical Address." The value to the right of it is the MAC address you're looking for. It's a sequence of 12 hexadecimal digits separated by hyphens or colons. For example, 00-1A-2B-3C-4D-5EThis is the data that needs to be entered into the router settings for filtering.
Retrieving data via PowerShell
For more advanced users or those who need to get information in a more readable form, the tool is great PowerShellThis is a more powerful shell that allows you to output data in a structured format, filtering out the extraneous information that the standard command produces. ipconfig.
Launch PowerShell from the Start menu search. To get a clean list of MAC addresses for all network interfaces, enter the following command:
Get-NetAdapter | Select-Object Name, MacAddressThis command will output a table where the adapter name will be listed (for example, Wi-Fi or Ethernet) and its corresponding MAC address. This is especially convenient if the computer has multiple network cards or virtual adapters from virtualization programs, such as VirtualBox or VMware.
You can also use the command getmac, which outputs information in an even more compressed form. Enter getmac /v to get detailed information, including the transport name and connection status. This method is useful because it immediately shows which address is being used for the current connection.
Finding an address in the Windows GUI
If working with the command line seems complicated or intimidating to you, you can always use the operating system's graphical interface. Windows 10 And Windows 11 Network settings are located in a separate settings menu, where all information is presented in a convenient format.
Right-click the network icon (monitor or Wi-Fi wave) in the system tray (near the clock) and select "Network & Internet settings." Next, go to the "Wi-Fi" (or "Ethernet," if necessary) section and click "Properties" or "Change adapter settings." In the window that opens, find the "Properties" button under the name of your connection.
In the dialog box that appears, the "Physical Address" field will appear at the very bottom. This is your adapter's MAC address. Newer versions of Windows also include a "Randomize Hardware Addresses" feature. If this switch is enabled, a temporary address will be used for the current network, and the real address will be hidden or listed separately as the "Real Physical Address."
- 📱 Right-click on the Wi-Fi icon in the tray.
- 📡 Select "Network & Internet settings" from the menu that appears.
- ⚙️ Go to the "Properties" of the active connection.
- 🔍 Find the "Physical Address" line at the bottom of the window.
It's worth noting that the menu location may vary slightly across OS builds. However, the logic remains the same: you need to access the properties of the active network interface. If you're using an enterprise version of Windows, some options may be hidden by the administrator.
☑️ Check network settings
Instructions for Android and iOS
Mobile device owners also often need to know the MAC address, especially when setting up guest access at a cafe or restricting children's access at home. This information is also available in mobile operating systems, but the path to it may not be obvious.
On devices running Android The path usually looks like this: open "Settings", go to the "About phone" (or "System") section, then select "Status" or "General". There you will find the "Wi-Fi MAC address" item. On some smartphones, for example Samsung or Xiaomi, the path may vary: "Settings" → "Connections" → "Wi-Fi" → click the gear next to the current network → "View more" → MAC address.
⚠️ Note: On Android 10 and newer, MAC address randomization is enabled by default for each new network. This means the router will see a different address for each new connection. To filter by MAC address on the router, you must either disable this feature in the Wi-Fi settings on your phone or use the actual address from the "Status" menu.
In devices Apple (iPhone, iPad) the situation is similar. Go to "Settings" → "General" → "About". There you will see "Wi-Fi Address". This is the actual hardware address. However, starting from iOS 14Apple also implemented a "Private Wi-Fi Address" feature. When enabled (which is recommended for security in public areas), a unique address will be generated for each network.
To view or change the address for a specific network on iPhone, go to Settings → Wi-Fi, tap the blue icon (i) next to the network name and toggle the "Private Wi-Fi address" switch. If you need to whitelist the device on the router, it's best to temporarily disable this feature or copy the address from the "About this device" section and use it as a permanent address.
| Platform | Path to settings | Nuance |
|---|---|---|
| Android 9 and below | Settings → About phone → Status | The address is always constant |
| Android 10+ | Settings → Wi-Fi → Gear → Advanced | Randomization needs to be disabled |
| iOS (iPhone/iPad) | Settings → General → About | Private Address feature |
| Windows 10/11 | Settings → Network → Properties | It may be hidden in cmd. |
Address determination on routers and Linux
If you don't have a Windows computer or smartphone handy but have access to your router, you can find the MAC address of connected devices directly in the router interface. This is often the easiest method, as it doesn't require entering complex commands on the client device.
Go to the router's web interface (usually at 192.168.0.1 or 192.168.1.1). Find the section labeled "Client List," "DHCP Server," "Status," or "Wireless Statistics." This will display a table of all devices currently connected to your network, along with their IP and MAC addresses. This is the ideal way to find out your TV's IP address. Smart TV or game consoles where it's difficult to navigate the menu.
For users of operating systems based on Linux (For example, Ubuntu, Mint, Debian) there are utilities. Open the terminal and enter the command ip link or ifconfig -aIn the command output, find your wireless interface (often called wlan0 or wlp2s0). Next to the mark link/ether the desired address will be indicated.
What should I do if the address in the router and in the system does not match?
This is a normal situation for modern operating systems. Most likely, the system has randomization enabled (private address). The router sees a temporary address, but the real one is listed in the system settings. For filtering, use the real address from the device settings.
Manufacturer's Identification Number (OUI)
The first six characters (three bytes) of a MAC address are called OUI (Organizationally Unique Identifier). They indicate the device manufacturer. Knowing this code allows you to identify the brand of the adapter, which is useful for network diagnostics when the list of connected devices includes unknown devices.
For example, if you see an address that starts with 00:1A:2B, and you know that this is the company code Asus, but you don't have devices from this brand, it's worth checking whether a neighbor has connected to your Wi-Fi. While modern routers often display the device's hostname, the MAC address provides more accurate technical information.
There are online OUI databases where you can enter the first six characters to retrieve the manufacturer's name. This helps identify smart plugs, cameras, or IoT devices that may have obscure names online.
Frequently Asked Questions (FAQ)
Is it possible to change the MAC address permanently?
Physically changing the MAC address hardcoded into the network card's chip is extremely difficult and requires specialized equipment. However, the operating system can programmatically override this address for all connections. In Windows, this is done through the Device Manager (Advanced tab → Network Address), and in Linux, with the command ip link set dev wlan0 address ...After rebooting, the software address is usually reset.
Is it safe to share your MAC address?
The MAC address itself isn't secret information like a password. It's easily discoverable by anyone within range of your Wi-Fi. However, with your MAC address, an attacker can clone it to bypass your network filtering or impersonate your device. Therefore, relying solely on MAC filtering as your sole network security isn't an option.
Why is my MAC address made up of letters and numbers?
A MAC address is written in hexadecimal notation. It uses the numbers 0 through 9 and the letters A through F. Each pair of characters represents one byte of information. The address contains 6 bytes in total, for a total of 48 bits of unique code.
What should I do if the MAC address field is empty or shows zeros?
If the system displays 00-00-00-00-00-00 If the address is missing, this indicates a problem with the network adapter drivers. Try reinstalling the Wi-Fi module drivers from the official website of the laptop or motherboard manufacturer. Also, check if the adapter is disabled in the BIOS/UEFI.
In conclusion, knowing how to find a MAC address is a basic skill for any user who wants to monitor their home network. Whether it's setting up parental controls, creating a guest area, or just curiosity, you now have all the tools you need to obtain this information on any device.
