How to Change MAC Address

Do you know what a MAC address is used for and how to change MAC address? If not, read this guide through to the end to learn how to modify your Android device’s MAC address. The process of changing a MAC address in Android is also known as Android MAC Spoofing.

Within a network, MAC addresses recognize your devices so that all the servers as well as the internet can know where to send data packets. Some applications and the internet also utilize mac addresses to monitor your device’s behavior. In order to become invisible and hide from other users and devices, avoid direct hacking, and several other reasons, changing your device’s Mac address is requested. This article thoroughly explains how to modify your Android device’s MAC address in order to increase your broadband speed, put a stop to hacking, remove app limits, and have fewer tracking activities.

What Is a MAC Address?

It stands for media access control address, which is an exclusive address made to identify each device present on a network. Each device on a particular network is identified exclusively by its MAC address, which is its physical address. Both an Internet Protocol address and a MAC address will be necessary in order to form communication between two networked devices. That is passed on to each device’s Network Interface Card, which then enables internet connectivity.

Due to the fact that it is globally unique, two devices cannot share the exact MAC address. Each device displays it in hexadecimal formats, such as 00:0b:35:9c:47:12. This 12-digit number is 48 bits long; the first 24 bits are utilized for the OUI, which stands for Organization Unique Identifier, and the remaining 24 bits are reserved for NIC/vendor-specific information.

 The MAC address operates on the OSI model’s data link layer and is supplied by the device’s manufacturer. It is included in its NIC, which is typically fixed and cannot be modified. An IP address is connected to a MAC address with the help of the ARP protocol.

What Is a MAC Address Used For?

The basic building blocks of your wire-based network are known as MAC addresses. All the network cards have different and unique MAC address of their own. Internet packets always come from a network interface and then they are sent to a MAC address. After a network adapter receives a packet, it starts comparing its own MAC address to the destination MAC address of the packet. The packet is processed if the addresses match and if not, it is thrown away.

There are special MAC addresses, such as the broadcast address ff:ff:ff:ff, which addresses every network adapter on the network. Internet service providers (ISPs), including cable companies and mobile providers, use MAC addresses in addition to internet and network data transmission processes to regulate bandwidth and other features on a particular device. Numerous apps, including cloud software, depend on MAC addresses to communicate with the device. They are also very helpful in tracking stolen devices. Moreover, location services like Google Maps use the MAC address of your device. The key takeaway is that MAC addresses are crucial to ensuring that the proper device receives the right data and that the connecting device or app communicates with the right one.

Based on the situation, hackers can be found on the network identical to that of your devices. Schools, public Wi-Fi hotspots, and businesses are places where the risk exists. Since the deceiver needs the real address to access your device, spoofing your Mac address inhibits direct hacking. A Mac address identifies your device on the network, similar to the way your SSN identifies you globally.

Ways to Check Your MAC Address on Android?

 Follow these steps in order to find the MAC address of your Android phone:

  1. Tap the Menu button to access Settings from the Home screen.
  2. Then click on About Phone.
  3. Depending on your phone model, click on Status or Hardware Information.
  4. Scroll down in order to view your WiFi MAC address.

Another way of finding it is:

  1. Tap the Connections option under Settings.
  2. Afterward, tap the Advanced button present in the top-right corner.
  3. The MAC address is located at the bottom of the Advanced options.

Reasons You Should Change Your MAC Address

Reason 1: To Make Your Identity Inaccessible on Public Networks

In order to protect your privacy while using wifi networks, anonymizing your MAC address in Android is crucial. These public wifi networks are usually a hacker’s playground where they may monitor your activity using your MAC address. While your MAC address will always remain the same, your local IP can be modified. Changing your MAC address before connecting to a network you don’t trust is strongly advised.

Reason 2: In Order To Get Through The Filter

There are a few wifi routers that use mac filtering. Even if you have the password in that situation, you cannot join the network since the router will only permit connecting devices that are on the whitelist. In that situation, in order to get beyond the filtering, we’ll need to modify the MAC address on Android or on our computer.

Reason 3: Bypassing ISP Firewall Rule

By changing it to a different device’s Mac address, you can trick your ISP in case it limits a device’s bandwidth, app use, or priority depending on the detected Mac address. Your spoof device can easily profit from the other device thanks to this method. Obviously, you will only be able to utilize either of the two devices that share the exact MAC address. By this way you can not only fool the ISP and but also get through the firewall.

Changing the MAC Address Using Root Access

Only the Android devices on which you have root access will allow you to change your Mac address. First, find out if your Android smartphone has root access.

  1. Find out the address of your MAC
  2. Install “BusyBox” and “Terminal Emulator for Android” from the playstore.
  3. Start the terminal emulator software, This app’s icon shows an Android robot in green hovering above a blue terminal screen.
  4. Type “su” there and then press “Enter.”
  5.  In case your device offers you to grant the app access to root, select “Allow.”
  6. To write down the address of the current network’s interface, type “IP link display” and press “Enter” once again. Your network interface’s name will be referred to as SBL9000 in this demonstration.
  7. Enter “busybox ip connect SBL9000” (replace SBL9000 with the actual name of your network). The MAC address will be shown after entering this command.
  8. You will now be able to see your new MAC address.
  9. Enter “busybox config SBL9000 hw ether XX:XX:XX:YY:YY:YY” in the terminal, substituting “XX:XX:XX:YY:YY:YY” with your new MAC address, then hit “Enter” to update the address.

Changing the MAC Without Using Root Access

In case you don’t have root access, follow these steps:

  1. Go to settings first, then WiFi.
  2. Now click the gear icon that you can see at the top of this screen. If it isn’t there, search for the “Configure WiFi” option and select it. Some Android systems offer an Advanced WiFi option where the MAC address can also be obtained.
  3. Note down the MAC address that is present at the bottom of this page.
  4. You must download Terminal Emulator for Android from the Google Play Store in order to obtain the interface name. 
  5. Open it up after downloading and installing.
  6. Enter the command as follows: ip link.
  7. Your screen will be overloaded with both valuable and irrelevant information. Now, keep in mind to write down your MAC address. Start searching for this MAC address under “link/ether” in every instance.
  8. The connection name is the one that corresponds to our MAC address. Either “wlan0” or “eth0” is used for the majority of devices.

We may now alter the MAC address using this terminal emulator since we are aware of our MAC address and the connection name. A correct MAC address should already be in your head or generated from this website before that. After you have formed a new MAC address, follow the procedures mentioned below:

  1. Activate the terminal emulator.
  2. Simply enter the command shown below: ip link set the MAC address you want to use as the wlan0 address at XX:XX:XX:YY:YY:YY, where wlan0 is the interface’s name.
  3. The manufacturer’s name should stay the same while modifying the MAC address, therefore the first three digits of the address should remain the same, or you may have several authentication problems.
  4. Your old MAC address will be restored when you restart your device because this is simply a temporary alteration.

Using Randomized MAC Address in Android

Mobile phone users now place high importance on security, especially those who use their smartphones for work. The security of Android gets better with each update, and that holds true for Android 10. Android smartphones provide the option of connecting to wifi using a random MAC address. This is a very important feature that you should use if you are serious about safeguarding your mobile device. However, it will only operate on smartphones with Android OS version 10 or higher. Employing this option while connecting to an unidentified wifi network will be advantageous. MAC randomization increases user privacy by preventing listeners from exploiting MAC addresses and compiling a history of device activity.

Here’s how to verify if the device is generating a random MAC address after you connect to a wireless network instead of your device MAC address.

  1. Select the Settings app.
  2. Then click on Network & Internet.
  3. Tap Wi-Fi.
  4. For the wireless network that needs to be established, tap the gear icon.
