Your IP address is a number that identifies your device on your home network

An IP address is a set of numbers separated by periods — something like 192.168.1.5 — that your router assigns to your computer so other devices can find it. You need to know your own IP address if you're troubleshooting network problems, setting up a printer on your network, or checking which devices are connected to your router. Windows gives you several ways to find it, and the fastest takes about 30 seconds.

Your IP address is not the same as your internet address. Your internet address (the one websites see) comes from your internet service provider. Your IP address is internal — it only matters inside your home network. Knowing it helps you understand what's happening on your own devices and network, which is part of staying aware of your setup's security.

Key Takeaways

  • The fastest way to find your IP address is to open Command Prompt and type ipconfig, then look for the line that says "IPv4 Address".
  • You can also find it by going to Settings > Network & Internet > Wi-Fi (or Ethernet), clicking your connection, and scrolling to "IP address".
  • If you see an address starting with 169.254, your device is not connected to your router properly and needs troubleshooting.
  • Knowing your IP address helps you identify your device when you're setting up network security or checking what's connected to your router.

Finding your IP address through Command Prompt

Open Command Prompt by pressing the Windows key, typing cmd, and pressing Enter. A black window will open. Type ipconfig and press Enter. You'll see a list of information about your network connections.

Look for the section labeled with your connection type — either "Ethernet adapter" if you're plugged in with a cable, or "Wireless LAN adapter" if you're on Wi-Fi. Under that section, find the line that says "IPv4 Address". The number next to it is your IP address. Write it down if you need it for setup or troubleshooting.

If you see multiple adapters listed, you may have more than one network connection. Your active connection (the one you're actually using) will have an IPv4 address. Inactive connections may show no address or a placeholder address.

Finding your IP address through Windows Settings

Click the Windows Start button and open Settings. Go to Network & Internet. If you're on Wi-Fi, click Wi-Fi in the left menu. If you're using a cable, click Ethernet.

You'll see a list of networks. Click the name of the network you're currently connected to. A details panel will open. Scroll down until you see "IP address" — the number shown there is your device's IP address on your home network.

This method is slower than Command Prompt but shows the information in a clearer format. It's useful if you prefer not to use the command line, or if you want to check other network details like your gateway address (the IP of your router) at the same time.

What different IP address ranges mean

Most home networks use IP addresses that start with 192.168 or 10.0. These are private addresses — they only work inside your home network. If you see an address starting with 169.254, your device is not properly connected to your router and needs troubleshooting. If you see something that starts with a different number entirely, check whether you're looking at the right network connection.

The last number in your IP address (the part after the final period) usually ranges from 1 to 254. Your router itself is often 192.168.1.1 or 10.0.0.1. Your devices get numbers above that. This doesn't affect security, but it helps you understand what you're looking at when you see a list of connected devices.

When you need your IP address for network setup

You'll need your device's IP address when you're setting up a printer, a security camera, or other equipment on your network. Some devices ask you to enter the IP address of the computer you want to connect to. You'll also need it if you're logging into your router's settings to change your Wi-Fi password or check which devices are connected.

If you're troubleshooting a network problem, your internet service provider or router manufacturer may ask for your IP address to help diagnose the issue. Having it written down saves time on the phone or in a support chat.

Checking your IP address on a laptop you don't use often

If you have a laptop that connects to your network only occasionally, its IP address may change each time it connects. This is normal — your router assigns a new address from its available pool. If you need a device to have the same IP address every time (for example, if you're setting up a printer), you can configure your router to assign a static IP address to that device. This is a router setting, not a Windows setting, and the steps vary by router model.

For most home uses, a changing IP address doesn't matter. Your devices find each other through your router regardless. But if you're doing network setup or troubleshooting, knowing whether an address is static or dynamic helps you understand what you're seeing.

Frequently Asked Questions

Is my IP address private information I should hide?

Your internal IP address (the one starting with 192.168 or 10.0) is only visible inside your home network. It's not private in the sense that it's secret — your router and all your devices know it. You don't need to hide it from people on your own network. Your internet-facing IP address (the one your internet provider assigns) is different and is visible to websites you visit.

Why does my IP address sometimes change?

Your router assigns IP addresses from a pool of available numbers. When a device disconnects and reconnects, it may get a different number. This is normal and doesn't affect how your network works. If you need a device to keep the same address, you can set a static IP in your router's settings.

What if I see two different IP addresses for the same device?

This usually means the device has both a wired connection (Ethernet) and a wireless connection (Wi-Fi) active at the same time. Each connection gets its own IP address. Most devices use only one at a time, but some may have both enabled. Check your network settings to see which connection is actually in use.

Can I change my IP address myself?

You can request a new IP address from your router by unplugging it for 30 seconds and plugging it back in, or by using the ipconfig /release and ipconfig /renew commands in Command Prompt. You cannot choose a specific address unless you configure your router to assign a static IP to your device.
