Detecting your mobile device's online ID is often a necessary step when setting up a home server, troubleshooting connection problems, or restricting access in parental controls. Users often confuse the concepts of external and internal addresses, which leads to errors in the configuration of routers. In this article we will analyze in detail the search algorithms for both types of identifiers on devices running Android.
Understanding the difference between these two values is critical for proper network organization. The local address is used for communication within your home or office network, while the external address determines your presence on the World Wide Web. We will look at both standard system utilities and advanced methods via the console.
Differences between local and external addresses
Before you begin your search, it is necessary to clearly distinguish between the two types of addressing used in modern networks. Local IP (often starting with 192.168.x.x) is issued by your router and is only visible to devices connected to the same access point. This address changes dynamically when reconnecting, unless static binding is configured.
The external address is the “face” of your network on the Internet. All devices connected to one router appear to external servers as one node with a common identifier. It is more difficult to find out, since this information is not stored in the settings of the smartphone itself, but is determined by the communication service provider.
⚠️ Attention: If your provider uses CG-NAT technology, then your external address will be common to hundreds of subscribers, which may interfere with the operation of some remote access services.
To correctly configure ports or organize video surveillance, you will need an external identifier, but to print documents or transfer files inside the apartment you need a local one. Confusion in these concepts often leads to users entering incorrect data into application settings.
To quickly check the network type, go to the browser: if the address begins with 10.x, 172.16.x or 192.168.x, you are behind the NAT of the router.
Search for local IP through system settings
The easiest and safest way to find out the internal address is to use the standard interface of the operating system. The path may differ slightly depending on the manufacturer's shell (MIUI, OneUI, ColorOS), but the general logic of the menu remains identical in all versions Android starting from 6.0.
You need to open the main settings menu and go to the section responsible for connections. Here the system displays the current network status and detailed connection information. Please note that the address is displayed only when there is an active connection to the access point.

Settings→Network and Internet(orConnections). - 📡 Select item
Wi-Fiand click on the name of your active network. - ℹ️ In the window that opens, find the field
IP addressin the “Advanced” or “Network information” section.
On some devices, for example Samsung Galaxy, the information is hidden inside the "Advanced" collapsible menu. On pure Android (Pixel, Motorola), the data is often visible immediately after clicking on the gear next to the network name. If the field is empty, try disconnecting and connecting again.
Using the terminal and command line
For advanced users who prefer to control each process, using a terminal emulator is an excellent solution. This method allows you to get the most accurate data about network interfaces, including those that are hidden in the graphical interface.
You will need to install a terminal application from the store Google Playfor example Termux or any other console emulator. After launching the application, you will have access to the shell Linuxbuilt into the system, where you can execute network commands.
ip addr show
By entering this command, you will see a list of all network interfaces. Find the block starting with wlan0 —this is your Wi-Fi module. The line inet will contain the required address with a subnet mask. This method is universal and works even on devices with a damaged settings GUI.
Alternate command for older versions of Android
If the ip command does not work, try the legacy ifconfig syntax. Enter ifconfig wlan0 and find the line inet addr.
Third-party applications for network diagnostics
If the built-in tools do not seem informative enough to you, the market offers many specialized utilities for network analysis. Such applications not only show the current address, but also scan the entire local network, identifying other connected devices.
Popular solutions such as Fing or Network Analyzerprovide real-time network visualization. They automatically detect the equipment manufacturer by MAC address and show the connection speed. This is especially useful when searching for “neighbors” who steal your traffic.
| Application | Main function | Presence of advertising | Root requirement |
|---|---|---|---|
| Fing | Network scanner | Yes (free version) | No |
| WiFi Analyzer | Channel analysis | Minimal | No |
| Termux | Terminal emulator | Absent | No |
| IP Tools | Set of utilities | Yes | Optional |
The use of third-party software is justified when in-depth diagnostics are required. However, remember that such applications request access to geolocation and a list of networks, which may cause concern among privacy-conscious users.
☑️ Criteria for choosing a network scanner
How to find the external IP address of a smartphone
Since the external address is not stored in the phone configuration, to obtain it you need to contact an external resource. The fastest way is to open your browser and enter the query “my IP” into the search bar. The search engine will instantly display your public identifier at the top of the search results.
There are also specialized services, such as 2ip.ru or whatismyip.comthat provide more detailed information: country, city, provider and connection type. This data is generated based on the request headers that your phone sends to the server.
⚠️ Attention: When switching from Wi-Fi to mobile data (4G/5G), your external IP address will change, since you will access the network through the gateway of your cellular operator, and not your home provider.
To automate this process, you can use the command line in terminal, if the package is installed curl. The command will request data from an external service and display only numbers, which is convenient for scripts.
curl ifconfig.me
This method saves traffic and time, since it does not require loading a full-fledged web page with advertising and scripts. It is ideal for a quick check when debugging network connections.
External IP is common to all devices in your Wi-Fi network, so you can check it from any gadget connected to the same router.
Solving problems with determining the address
Sometimes users are faced with a situation when the phone is connected to the network, but the IP address is not assigned or appears as 0.0.0.0. This indicates a malfunction of the protocol DHCP, which is responsible for the automatic distribution of addresses.
First of all, try to forget the network and connect again by entering the password. If this does not help, check the date and time settings: clock desynchronization may block the establishment of a secure connection with authentication servers.
- 🔄 Reboot the router and smartphone - this solves 90% of problems with freezing network services.
- ⚙️ Try setting a static IP in the Wi-Fi settings by specifying the address manually (for example, 192.168.1.55).
- 🛡️ Disable VPNs and proxy servers that can intercept network traffic and hide real data.
In rare cases, the problem lies in incompatible encryption standards. Try changing the security type on the router from WPA3 to WPA2, as older phone models may not work correctly with new protocols.
Address conflict
If you manually entered an address that is already occupied by another device on the network, an IP conflict will occur. The Android system will warn you about this with a pop-up notification.
Is it possible to change the phone's IP address without changing the network?
Yes, it is possible. To change the local address, just disconnect from Wi-Fi and connect again - the router will issue a new address from the pool. To change the external address, the easiest way is to turn on and off the “In Flight” mode for 10 seconds or reboot the router if your provider dynamically issues addresses.
Why do you need to know the MAC address if you have an IP?
MAC address is a unique physical identifier of a network card that does not change (except for the randomization function in new Androids). It is used to filter access at the router level, while the IP address can change with each connection.
Is my IP address visible to the sites I visit?
Yes, any web server sees your external public IP address, since that is where data packets with the requested pages are sent. You can only hide it using a reliable VPN service or the Tor network.
Why does the settings show IPv6 instead of IPv4?
This means that your ISP and router support the new addressing standard. IPv6 provides a virtually unlimited number of addresses. Most modern services work correctly with both protocols at the same time.
