How to Find the IP Address of a Device Connected to Wi-Fi: A Complete Guide

Have you ever encountered a situation where you urgently need to find Device IP address on your Wi-Fi network? You might be setting up smart home, trying to connect to a network printer, or simply want to block someone else's device from using your router. In any case, knowing the IP addresses of all connected devices can be extremely useful.

In this article we will look at all current methods for determining IP addresses From standard operating system tools to specialized apps and router functions, you'll learn how to find the IP address of a phone, laptop, TV, or even a hidden camera connected to your network. We'll also explain why devices sometimes receive different addresses and how to fix this.

It is important to understand that there are two types of IP addresses: external (public), which are visible on the Internet, and internal (local), used within your home network. Today we'll be talking specifically about local addresses, which begin with 192.168.x.x, 10.x.x.x or 172.16.x.x.

1. How to find your device's IP address (Windows, macOS, Android, iOS)

Let's start with the simplest thing—determining the IP address of the device you're reading this article from. The methods vary depending on the operating system, but they all take less than a minute.

On Windows 10/11 The fastest way is to use the command line. Click Win + R, enter cmd and run the command:

ipconfig

Find the block in the results Wireless LAN adapter (or Ethernet, if connected via cable) and a line IPv4 addressThis is your local IP.

On macOS open System Preferences → Network, select the active connection and see the IP address in the status. An alternative way is to run in Terminal:

ifconfig | grep"inet"

For Android go to Settings → Network & Internet → Wi-Fi, tap on your network and select Additionally. The IP address will be listed in the section Network data.

On iPhone/iPad the path is this: Settings → Wi-Fi, click on the symbol i next to your network - the IP address will be displayed in the block IPv4 address.

2. Viewing the list of devices through the router's web interface

The most reliable way to see all devices on your network - go to the router settings. Most modern models (TP-Link, ASUS, Keenetic, MikroTik) show not only IP addresses, but also MAC addresses, device names, and even connection history.

The instructions are universal for most routers:

1. Find out the IP address of your router (usually it is 192.168.0.1 or 192.168.1.1).
2. Enter it in the address bar of your browser and log in (default logins/passwords are indicated on the router sticker).
3. Find the type section DHCP clients, List of devices or Local area network.

Here's what it looks like on popular models:

What should I do if my router doesn't show all my devices?

Sometimes, not all devices are displayed in the DHCP client list. There may be various reasons:

1. The device has a static IP not obtained via DHCP.

2. The gadget is connected via a guest network (if it is configured separately).

3. The router does not have time to update the list (try rebooting it).

4. The device uses a VPN or proxy to mask its presence on the network.

If you can't find the section you need, use the router settings search (usually the magnifying glass icon at the top of the page) and enter keywords: DHCP, clients or devices.

3. Using network scanners (for advanced users)

When standard methods don't work (for example, the router doesn't show hidden devices), specialized programs come to the rescue - network scannersThey analyze network traffic and detect all active IP addresses, even those that are not listed in the DHCP list.

Here are the top 3 free utilities for different platforms:

• 🖥️ Advanced IP Scanner (Windows) — Scans an IP range, displays MAC addresses and device names. Can identify the manufacturer by MAC address.
• 📱 Fing (Android/iOS) — a mobile app with network visualization. It can detect hidden cameras and vulnerable devices.
• 🐧 nmap (Linux/macOS/Windows) - a command-line tool for professionals. Scanning command:
  

  nmap -sn 192.168.1.0/24

The advantage of scanners is that they show all active devices, including those that don't use DHCP. For example, they can be used to find:

• 📷 Network cameras connected directly to the router
• 🖨️ Printers or MFPs with static IP
• 🎮 Game consoles (PlayStation, Xbox, Nintendo Switch)
• 💡 Smart home devices (lamps, sockets, thermostats)

Make sure your device is connected to the same network as the target devices.

Close unnecessary programs using the network

Write down your network's IP address range (usually 192.168.x.1-254)

Check that your antivirus isn't blocking the network scanner.

Please note: some devices (especially IoT gadgets) may not respond to ping requests, so the scanner won't see them. In this case, analyzing the router's ARP table or intercepting traffic using Wireshark.

4. How to find the IP address of a specific device (TV, printer, camera)

If you need to know the IP of only one device (for example, Smart TV (or a network printer), the easiest way to find it is in the gadget's settings. Here are instructions for popular types of devices:

For Smart TV (Samsung, LG, Sony, Xiaomi):

• 📺 Press on the remote control Menu → Settings → Network → Network Status.
• 🔍 The IP address will be listed next to the connection details (may be called IP address or Local address).
• ⚙️ On some models (Samsung QLED) you need to go to Support → Contact Information.

For network printers (HP, Canon, Epson, Brother):

• 🖨️ Click the button Wi-Fi or Net on the printer panel.
• 📄 Print Network report or Self Test — there will be an IP.
• 💻 Alternatively: install proprietary software (for example, HP Smart) - it will automatically find the printer on the network.

For IP cameras (Hikvision, Dahua, Xiaomi):

• 🎥 Use proprietary software (for example, iVMS-4200 For Hikvision).
• 🔍 Check the sticker on the camera body - sometimes the IP is indicated there.
• 📡 If the camera is connected via PoE, its IP can be found in the switch settings.

5. Determining IP by MAC address (for network administrators)

If you know MAC address If you don't know the device's unique network card identifier (NIC) but don't know its IP address, you can use the ARP (Address Resolution Protocol) table. This method works on Windows, Linux, and macOS.

IN Windows run in command line:

arp -a

You'll see a list of all devices your computer has recently interacted with, along with their IP and MAC addresses. If the MAC address you need isn't listed, first ping the suspected IP:

ping 192.168.1.100
arp -a

On Linux/macOS use:

arp -n

To update the ARP table, first run:

sudo arp-scan --localnet

MAC addresses are usually found on device labels or in their settings. For example:

• 📱 On Android: Settings → About phone → General information → Wi-Fi MAC address
• 💻 On Windows: ipconfig /all (look for the line Physical address)
• 🖥️ On macOS: System Information → Network → Wi-Fi → Ethernet Address

6. Problems and solutions: why the device is not visible on the network

Sometimes, even after all these steps, the desired device doesn't appear in the list of connected devices. Here are some possible causes and solutions:

Problem 1: The device does not receive an IP address

⚠️ Important: If your device connects to Wi-Fi but doesn't access the internet, check your router's DHCP settings. The address pool may be exhausted or the DHCP server may be disabled.

• 🔄 Reboot your router and device.
• 📱 Forget the network on your device and reconnect.
• 🛠️ Check your router settings to see if DHCP is enabled (Local Network → DHCP Settings).

Problem 2: Device with static IP is out of network range

If you have manually set the IP address (for example, 192.168.1.200), and the router distributes addresses only up to 192.168.1.100, the device will not be visible on the network. Solution:

• 🔧 Change the static IP on the device so that it falls within the DHCP range.
• 📡 Or expand the range of distributed addresses in the router settings.

Issue 3: The device is connected to a guest network

Many routers have a separate guest network with its own IP range (for example, 192.168.2.x). Devices from the guest network are not visible on the main network, and vice versa. Check:

• 🔍 In the router settings section Guest network or Additional network.
• 📡 Connect the device to the main network (the password is usually indicated on the router sticker).

Problem 4: Firewall or antivirus is blocking detection

Some security programs (eg. Kaspersky, ESET) may block network scanning. Solution:

• 🛡️ Temporarily disable your antivirus and repeat the scan.
• 🔒 Add the network scanner to your firewall exceptions.

7. Security: How to protect your network from unauthorized devices

Knowing the IP addresses of devices on your network is not only diagnostic, but also safety elementIf you find unfamiliar devices in the list of connected gadgets, this may mean that:

• 🔓 Someone connected to your Wi-Fi knowing the password.
• 🕵️‍♂️ Your router is infected with malware (for example, VPNFilter).
• 🏠 Neighbors are using your network because of weak encryption.

What to do if you find a suspicious device:

1. 🔍 Check the MAC address using a search engine (the first 6 characters indicate the manufacturer).
2. 🚫 Block it in your router settings (Security → MAC Filtering).
3. 🔑 Change your Wi-Fi password to a more complex one (at least 12 characters with numbers and special characters).
4. 🛡️ Turn on WPA3 instead of WPA2 (if the router supports it).
5. 🔄 Update your router firmware to the latest version.

For additional protection:

• 📵 Turn off WPS - This protocol is vulnerable to brute force attacks.
• 🌐 Set up VLAN for guest network (if the router supports it).
• 📡 Hide network SSID (Hide access point) - is ineffective, but adds complexity to random connections.

FAQ: Frequently Asked Questions about Wi-Fi IP Addresses

❓ Is it possible to find out the IP address of a device if it is turned off?

No, an IP address is assigned to a device only when it's connected to the network. If the device is turned off, its IP can be transferred to another device via DHCP. However, some routers (e.g., Keenetic) the connection history is saved with the last known IP.

❓ Why does my device's IP address constantly change?

This is normal behavior when using DHCP. The router assigns IP addresses from a specified range for a limited time (lease time, usually 24 hours). To assign a permanent IP address:

1. Set up a static IP on the device itself.
2. Or reserve the IP address for the device's MAC address in the router's DHCP settings.

❓ Is it possible to determine the device model by its IP address?

No, you can't determine the model from the IP address itself. However, MAC address (which is often displayed next to the IP address on a router) can be used to identify the manufacturer. The first 3 bytes of the MAC (OUI) are assigned to vendors. For example:

• B8:27:EB — Raspberry Pi
• 78:31:C1 — Apple (iPhone, MacBook)
• 50:65:83 — Samsung (smartphones, TV)

A complete list of OUIs can be found on the IEEE website or through online services such as MAC Vendors.

❓ How do I find a device's IP address if it's connected via VPN?

If a device uses a VPN, its local IP address on your network will remain the same, but all traffic will be routed through the VPN server. You can detect such a device:

• For active connections in the router (traffic will go to the VPN server IP).
• Through port analysis (VPN often uses ports 1194, 1723, 443).
• Specialized tools like Wireshark (skills in working with network protocols will be required).

Regular network scanners (like Advanced IP Scanner) VPN traffic not Detect.

❓ Is it legal to scan other people's networks for devices?

Scanning his own Network scanning is completely legal. However, scanning other people's networks (for example, your neighbors' Wi-Fi) may qualify as:

• Violation of the Law "On Personal Data" (if information about users is collected).
• Unauthorized access to computer information (Article 272 of the Criminal Code of the Russian Federation).
• Violation of the provider's network usage rules (may result in blocking).
