“MAC” stands for “Media Access Control,” this address is used to identify your device. The MAC address assigns to your network adapter. You need this to be able to use the Internet via LAN or WLAN. The 12-digit code is displayed in the hexadecimal system and is unique to your device. The first six digits indicate from which manufacturer. Using Windows 10: Connect to a network. This method is only applicable if you are currently. In computer networking, the Media Access Control (MAC) address is every bit as important as an IP address. Learn in this article how MAC addresses work and how to find the MAC addresses being used by a computer. What Is a MAC Address? The MAC address is a unique value associated with a network adapter.
To communicate with a Wi-Fi network, a device must identify itself to the network using a unique network address called a media access control (MAC) address. If the device always uses the same Wi-Fi MAC address across all networks, network operators and other network observers can more easily relate that address to the device's network activity and location over time. This allows a kind of user tracking or profiling, and it applies to all devices on all Wi-Fi networks.
To reduce this privacy risk, iOS 14, iPadOS 14, and watchOS 7 use a different MAC address for each Wi-Fi network. This unique, static MAC address is your device's private Wi-Fi address for that network only.
Join Wi-Fi networks with a private address
Using a private Wi-Fi address doesn't affect how you join or use most Wi-Fi networks. Connect to Wi-Fi as you normally do.
- If your Wi-Fi router is configured to notify you whenever a new device joins the network, you will be notified when your device first joins with a private address.
- If a network can't use a private address to provide parental controls or identify your device as authorized to join, you can stop using a private address with that network.
- Rarely, a network might allow you to join with a private address, but won't allow internet access. If that happens, you can stop using a private address with that network.
Turn private address off or on for a network
You can stop or resume using a private address with any network. For better privacy, leave the setting on for all networks that support it.
iPhone, iPad, or iPod touch
- Open the Settings app, then tap Wi-Fi.
- Tap the information button next to a network.
- Tap Private Address. If your device joined the network without using a private address, a privacy warning explains why.

- Open the Settings app, then tap Wi-Fi.
- Tap the name of the network you joined. If you haven't joined the network yet, swipe left on its name and tap more .

Mac Addresses Are Used As
- If you erase all content and settings from your device, or you use the Reset Network Settings feature, your device will use a different private Wi-Fi address the next time it connects to the Wi-Fi network.
In order to communicate or transfer the data from one computer to another computer we need some address. In Computer Network various types of address are introduced; each works at different layer. Media Access Control Address is a physical address which works at Data Link Layer. In this article, we will discuss about addressing in DLL, which is MAC Address.
Media Access Control (MAC) Address –
MAC Addresses are unique 48-bits hardware number of a computer, which is embedded into network card (known as Network Interface Card) during the time of manufacturing. MAC Address is also known as Physical Address of a network device. In IEEE 802 standard, Data Link Layer is divided into two sublayers –
- Logical Link Control(LLC) Sublayer
- Media Access Control(MAC) Sublayer
MAC address is used by Media Access Control (MAC) sublayer of placeholder='Add your personal notes here! (max 5000 chars)'>
