In today's digital world, knowing how to determine the IP address of a WiFi network or router is a basic skill for any user wanting to manage their home network. Situations often arise where you need to configure port forwarding, restrict guest access, or simply diagnose connection issues, and all of these actions require precise network coordinates for your equipment. Without understanding the addressing structure and how to obtain it, effective local network management becomes impossible.
Many users confuse the public IP assigned by their ISP with the local gateway address used within their home or office. In this article, we'll detail how to find both types of addresses on various devices, from Windows computers to Android and iOS mobile devices. You'll learn how to use built-in operating system tools and specialized utilities to get a complete picture of your network.
Understanding IP addressing in a local WiFi network
Before we move on to practical actions, it is necessary to clearly understand the difference between public And local Address. A public IP (White IP) is a unique identifier assigned by your ISP for your entire home or office; it's how websites recognize you online. A local IP (Private IP) is used within your WiFi network for communication between your router, laptops, smartphones, and smart light bulbs.
Typically the router acts as default gateway and has a static local address, often 192.168.0.1 or 192.168.1.1All other devices receive their addresses automatically via the protocol. DHCP, which is configured on the router. It is the local gateway address that is most often needed to access the WiFi settings control panel.
It's important to note that private address ranges are strictly regulated by RFC standards. If you see an address starting with 10., 172.16.–172.31. or 192.168., then you're within the local network. Public addresses can be anything, and changing them often requires contacting your provider or using special services.
⚠️ Note: Some providers use CGNAT technology, which causes your router to receive a "private" local address even on the external network. In this case, direct access from the internet to your home WiFi will be impossible without additional configuration on the provider's end.
Finding the IP address of a router and devices in Windows
Windows users have several proven methods for obtaining necessary network data. The fastest and most reliable method is using the command line, which provides access to low-level information about network interfaces. This method is universal for all versions of Windows, from XP to the latest Windows 11.
The second option is suitable for those who prefer a graphical interface and don't want to remember commands. The Network and Sharing Center provides detailed information about the connection status, including the physical address (MAC) and IP addressing. Both methods allow you to calculate not only the computer's address but also main gateway, which is the address of your WiFi router.
Let's look at the step-by-step algorithm of actions via the console. Open the Start menu, enter cmd and press Enter. In the black window that appears, enter the command ipconfigThe system will display a list of all network adapters. Find the section corresponding to your WiFi connection (usually called "Wireless Network" or "Wireless LAN Adapter").
C:\Users\User> ipconfig
Wireless Network Adapter Wireless Network:
IPv4 address.........: 192.168.1.45
Subnet mask.........: 255.255.255.0
Default gateway: 192.168.1.1
In the output list we are interested in two lines: IPv4 address (this is the address of your PC on the network) and Main gateway (This is the router's address). Remember or copy the gateway address—you'll need it to access the settings. If you need to find the IP address of another device on the network, such as a printer or camera, it's more difficult to do using standard Windows tools, but you can use the command arp -a, which will show a table of IP and MAC addresses of devices known to the system.
☑️ Checking your network connection in Windows
Finding IP addresses on Android and iPhone smartphones
Mobile devices are among the most active consumers of WiFi traffic, and the need to know their address or the router's address often arises. On Android smartphones, the interface may differ depending on the manufacturer's operating system (Samsung One UI, Xiaomi MIUI, stock Android), but the search logic remains the same.
On iPhone (iOS), Apple provides a very clear and user-friendly interface for viewing network parameters. Users don't need to be experts to find the information they need; they simply navigate to the relevant WiFi settings menu. This is especially useful when quickly checking whether your phone's address conflicts with another device on the network.
For Android users, the path usually lies through the settings menu. Go to Settings → Connections → WiFiClick on your network name or the gear icon next to it. In the menu that opens, select "Advanced" or scroll down to the "Network" section. There you will see the fields IP address And Gateway.
iPhone owners need to open Settings → Wi-FiNext to the name of the connected network, click the blue information icon (the letter "i" in a circle). The menu that opens will contain the "IP Address" section, which displays the device information, and the "Router" section, which contains the IP address of your WiFi access point.
Using the Command Prompt and Terminal on macOS and Linux
Users of Apple computers and Linux operating systems have powerful network diagnostic tools right out of the box. The terminal on these systems allows for more than just address tracing, but also in-depth traffic and connection analysis. For macOS, the commands are largely similar to those in Linux, making the work easier for cross-platform specialists.
In macOS, the most informative command is ifconfig, although in modern versions it is gradually being replaced by the utility ip (via Homebrew) or command networksetupHowever, the classic method still works. Open Terminal (via Spotlight or in the Applications folder) and enter the command. You'll get detailed output about all interfaces.
en0: flags=8863 mtu 1500
options=400
ether ac:de:48:00:11:22
inet 192.168.1.55 netmask 0xffffff00 broadcast 192.168.1.255
In Linux distributions (Ubuntu, Debian, Mint), the command has become the de facto standard ip addr or its abbreviation ip aIt shows the status of all network interfaces. To find the router (gateway) address in Linux, it's more convenient to use the command ip route or netstat -rnThe first line of output usually contains the word default via, followed by the desired gateway IP address.
Also worth mentioning is the utility nmcli (Network Manager Command Line Interface), which is available in many Linux distributions with a graphical shell. The command nmcli device show will give a structured list of all connection parameters, including DNS servers and IP addresses, which may be easier to read than the raw output ifconfig.
Table of standard addresses of popular routers
If you can't access settings via automatic gateway detection, knowing the factory default addresses often helps. Network equipment manufacturers often use standard ranges to simplify initial setup. Below is a table of the most common addresses.
| Manufacturer | Standard IP address | Alternative address | Default login |
|---|---|---|---|
| TP-Link | 192.168.0.1 | 192.168.1.1 | admin |
| ASUS | 192.168.1.1 | router.asus.com | admin |
| D-Link | 192.168.0.1 | 192.168.1.1 | admin |
| Netgear | 192.168.1.1 | 192.168.0.1 | admin |
| Keenetic | 192.168.1.1 | my.keenetic.net | admin |
It's worth keeping in mind that if the network was previously configured by another administrator, the default addresses may have been changed for security reasons or to avoid conflicts. In this case, the methods described in the Windows and macOS sections (via ipconfig or ifconfig), are the only correct ones for determining the current gateway address.
⚠️ Note: If standard addresses (192.168.0.1 or 1.1) don't open the setup page, your network may be using a non-standard subnet. Use the gateway command on the connected device to find the exact address.
Specialized programs and network scanners
For those who need to calculate the IP addresses of all devices on a WiFi network simultaneously, manual methods can be too labor-intensive. Specialized scanner utilities come to the rescue. They send requests to all possible addresses in a range and collect responses from active devices, displaying their MAC addresses, manufacturers, and names.
One of the most popular programs for Windows is Advanced IP ScannerIt's free, requires no installation, and works incredibly fast. Just click the "Scan" button, and in a few seconds you'll see a complete map of your network. It's the perfect tool for finding "unknown" devices that may have connected to your WiFi without permission.
There are similar applications for mobile platforms, for example, Fing or Network AnalyzerThey not only display a list of devices, but also allow you to run speed tests, check open ports, and identify the device type (TV, phone, printer) based on its network behavior.
Why do you need a MAC address?
A MAC address is a unique physical identifier for a network card, assigned by the manufacturer. Unlike an IP address, which can change, a MAC address is (usually) constant. Scanners use it to identify the device manufacturer (the first six characters of the MAC address identify the vendor).
Using such programs is especially important in large apartments or offices where dozens of connected devices are connected. They allow for quick identification of address conflicts, where two devices are assigned the same IP address, leading to connection interruptions.
Common problems and solutions
When calculating IP addresses, users often encounter typical errors. One of the most common is the lack of response from the gateway. If the command ping If the request doesn't work and the address is determined correctly, it's possible that the router has the ICMP request blocking feature enabled or the device is frozen.
Another issue is having multiple network adapters. A laptop might have WiFi, an Ethernet cable, and a virtual adapter from a VPN or virtual machine active simultaneously. In the command line, carefully check the interface name to avoid confusing the addresses of different networks.
It's also worth mentioning the issue of "gray" addresses from ISPs. If you're trying to figure out your public IP for remote access, but your ISP uses CGNAT, you'll see an address from the range 100.64.0.0 – 100.127.255.255This is a reserved range for ISP networks and is not routable on the Internet.
⚠️ Note: Router interfaces and operating system menus are subject to update. The layout of menu items and the appearance of settings windows may differ from those described in the instructions. Always consult the official documentation for your specific device model.
FAQ: Frequently Asked Questions
Can my router's IP address change on its own?
A router's local IP address (gateway) is usually static and preset by factory settings. It doesn't change unless you reflash the router or reset it to factory settings, if it was changed before the reset. However, the public IP address seen by the internet can be dynamic and change each time the router reconnects to the ISP, unless you ordered a static IP address.
What should I do if I forgot my WiFi password but know the router's IP address?
Knowing your router's IP address allows you to access its web interface (control panel). To do this, enter the address in your browser. If you know the router's administrator login and password, you can view or change the wireless network password in the Wireless or WiFi settings. If you've forgotten the administrator password, you'll need to reset the router using the reset button on the router.
Is it safe to show your IP address to other people?
A local IP address (e.g., 192.168.1.5) is secure and only works within your home. A public IP address is visible to all websites you visit. While it doesn't grant hackers full access, it can be used for approximate geolocation and DDoS attacks. For increased privacy, a VPN is recommended.
How to find the IP address of a printer on a network?
The easiest way is to print a network configuration report from the printer itself (usually via an on-screen menu or a key combination). Alternatively, use a network scanner (as mentioned above) or check the list of DHCP clients in the router settings—the printer's name and its current IP address will be listed there.
