How to find the MAC address of a phone connected to Wi-Fi

In modern home networks, where multiple devices are simultaneously connected to a single router, it is often necessary to identify a specific gadget. MAC address The Media Access Control Address (MAC) is a unique identifier for a network card that allows a network administrator or router owner to accurately determine which device is currently active. Knowing how to find this code is critical for setting up parental controls, filtering traffic, or detecting unauthorized access.

Many users mistakenly believe that this information can only be obtained by simply picking up the phone, but this is not true. There are several ways to obtain device data remotely through the router's control panel or using specialized software. Physical address The device's ID does not change when reconnecting to the network (unless the randomization feature is enabled), making it a reliable marker for tracking.

In this article, we'll cover all available methods in detail: from logging into the router's web interface to using the command line and mobile apps. You'll learn how to distinguish real devices from the client list and understand why you need them. MAC filtering to protect your home network from outsiders.

What is a MAC address and why should you look for it on the network?

Media Access Control A MAC address is a physical address assigned to a network interface by the equipment manufacturer. Unlike an IP address, which can change with each reconnection or reboot of the router, a MAC address is hardcoded into the network module's chip. This makes it an ideal tool for identifying a specific phone or tablet in a list of connected clients.

When you wonder how to find out the MAC address of a phone connected to WiFi, you are actually looking for this hexadecimal code, which consists of 12 characters (for example, A1:B2:C3:D4:E5:F6). The first six characters (OUI) indicate the device manufacturer, and the rest are a unique serial number. This information allows you to distinguish, say, a smartphone. Samsung from a smart light bulb Xiaomi without having to check hostnames, which are often unreadable (e.g. android-df45a2).

The main reason for looking for this setting is security and traffic management. If you suspect your neighbors are "stealing" your internet, or want to limit your children's online time, you need to know the exact ID of their devices. Without this setting, setting up rules Access Control (Access control) is not possible in the router.

⚠️ Attention: In modern versions of operating systems (iOS 14+, Android 10+), the "Private Wi-Fi Address" feature is enabled by default. This means the phone can generate a random MAC address for each new network, hiding its real physical identity.

Searching for a device via the router's web interface

The most reliable and universal way to see which devices are on your network is to log into your router's admin panel. This method doesn't require installing any additional software and works from any computer or phone connected to the same network. You'll need a browser and the default gateway address, which is usually found on a sticker on the bottom of the device (most often 192.168.0.1 or 192.168.1.1).

After entering your login and password (the standard ones are often admin/admin(if you haven't changed them) you need to find the section responsible for the wireless network. Depending on the router model (TP-Link, Asus, Keenetic, MikroTik), this section may have different names. Look for tabs labeled "Wireless," "WLAN," "Status," "Client List," or "DHCP Server."

The list that opens will display all active connections. Here you will see the IP address, device name (Hostname), and the desired connection. MAC addressIf the device name is illegible, the manufacturer's address (the first three pairs of characters) will help you understand what kind of gadget it is. For example, codes starting with Apple, Samsung or Huawei, they will give you a hint right away.

It is worth noting that in some advanced firmware, such as OpenWRT or DD-WRT, you can see not only current clients but also connection history. This is useful for retrospective analysis, if you want to know who connected to the network yesterday or an hour ago.

Using network scanners on a PC and smartphone

If logging into your router seems too complicated or you don't have access to the administrator password, you can use third-party scanning utilities. These programs scan your local network and provide detailed information about all visible devices. For a computer, a great choice is Advanced IP Scanner or Angry IP Scanner, which work quickly and do not require installation.

There are many apps available for smartphones (Android/iOS) such as Fing or Network AnalyzerThey allow you to see a list of all Wi-Fi devices in one click. The app will show not only MAC address, but also the manufacturer, open ports, and even the device model if it is determined through the OUI database.

These scanners operate simply: they send ARP requests to all possible addresses on the subnet and wait for a response. A device that responds to the request provides its physical address. This allows for a complete picture of the network in seconds, even if some devices have hidden their names.

Why might the scanner not see some devices?

Some routers have an "AP Isolation" feature that prevents devices within the network from "seeing" each other. In this case, the phone scanner will only show the router itself and the internet gateway, but not other phones or TV boxes. For the scanner to work, this feature must be disabled in the router settings.

It's important to understand that using scanners on other people's networks without permission can be considered a security breach. Use these tools only on your personal network or on a network where you have administrator rights.

How to find the MAC address on your device (Android and iOS)

If you have physical access to the phone, the easiest way is to view the settings directly on the device. This eliminates any identification errors. On smartphones running Android the path usually looks like this: Settings → About phone → General information or Settings → Connections → Wi-Fi → (gear) → Advanced.

In devices Apple iPhone The situation is a little more complicated due to privacy policy. To see the address, you need to go to Settings → General → AboutHowever, please note: this is the physical address of the Wi-Fi module. If the "Private Wi-Fi Address" feature is enabled in the specific Wi-Fi network settings, the router will see a different, random address.

To disable randomization on iPhone, you need to go to the settings of a specific Wi-Fi network (via the icon (i) next to the network name) and turn off the toggle switch Private Wi-Fi AddressAfter reconnecting, the device will use its real, factory MAC address, which matches the one specified in the "About this device" section.

Manufacturer's Identification Number (OUI) Mapping Table

When analyzing the list of connections on a router, you'll often see only hexadecimal codes. To determine the brand of the device, you can use the first three pairs of characters in the MAC address. This is called the OUI (Organizationally Unique Identifier) ​​prefix.

Below is a table of the most common prefixes you'll encounter on your home network. Knowing these codes will help you quickly filter your devices from those of others.

It's worth keeping in mind that major manufacturers can have dozens of different prefixes registered to different subsidiaries. Therefore, an exact match of the first six characters is a guarantee of brand identity, but the absence of an exact match in the short table doesn't mean the device isn't from that manufacturer.

Identification Problems: Randomization and Hidden Networks

Modern privacy protection technologies pose certain challenges for home network administrators. The MAC address randomization feature implemented in Android and iOS is designed to protect against user tracking in public places. However, at home, this becomes a problem: the phone may appear as a new device to the router each time.

If you see multiple devices with names like Unknown, Android If you have a phone with a different MAC address or strange character sets, and their number exceeds the number of your devices, this is most likely a randomization effect. In this case, the only way to find out the "true" MAC address of a phone connected to Wi-Fi is to temporarily disable this feature in the Wi-Fi settings on the phone itself.

Another complication is hidden SSIDs. If a network is hidden, some simple scanners may not reveal the network name, but the MAC address of the access point and connected clients will still be visible in traffic. For the average user, this means that hiding the network name is not a reliable method of protection against "neighbors" who know how to use packet sniffers.

⚠️ Attention: Router and mobile OS interfaces are constantly being updated. The layout of menu items may differ from what's described. If you can't find the setting you need, check the official documentation for your device model or firmware.

FAQ: Frequently Asked Questions

Is it possible to change the MAC address on a phone?

Yes, on Android, this can be done via root access or special apps (requires unlocking the bootloader). On iOS, you can't change the physical address without jailbreaking, but you can use the "Private Wi-Fi Address" feature, which changes it programmatically for each network.

Why does the router have two MAC addresses for one phone?

Most likely, the phone is connected to the network via both 2.4 GHz and 5 GHz, and the router sees them as two different interfaces. Or, the randomization feature is enabled, and the phone is using different virtual addresses.

Is it dangerous to share your MAC address?

The MAC address itself doesn't grant access to your data, photos, or passwords. However, with it, an attacker could attempt to clone the address to bypass your router's filtering (if you have a whitelist) or track your online activity.

How to block a phone by MAC address?

In your router settings, find the "Filter," "Access Control," or "Blacklist" section. Add the MAC address of the unwanted device and apply the rules. The router will then ignore connection requests from that device.
