What an IP address is and why you need yours

An IP address is a number that identifies your device on your home network — like a mailing address for data. When you set up a find network, you sometimes need to know your device's IP address to log into your router, configure security settings, or troubleshoot why something isn't connecting.

Every device on your network has one: your laptop, phone, tablet, printer, and smart TV all get assigned an IP address when they join. Your router hands these out automatically, so you don't have to set them manually. But finding the address your router assigned to a specific device takes a different path depending on whether you're using Windows, Mac, iPhone, or Android.

The address you're looking for is your local IP address — the one that works only inside your home network. It usually starts with 192.168 or 10.0. This is different from your public IP address, which your internet provider assigns and which the outside internet sees.

Key Takeaways

  • Your local IP address is a number your router assigns to identify your device on your home network, usually starting with 192.168 or 10.0.
  • On Windows, open Settings, go to Network & Internet, then Status to find your IPv4 address listed there.
  • On Mac, open System Settings, click Network, select your connection, and look for the IP address shown in the details pane.
  • On iPhone or iPad, go to Settings, tap Wi-Fi, select your network name, and the IP address appears under the network details.
  • On Android, open Settings, go to Wi-Fi, long-press your connected network, and tap Modify to see the IP address.

Finding your IP address on Windows

Open the Settings app by pressing the Windows key and typing "Settings," then press Enter. Click on Network & Internet in the left sidebar.

Select Status from the menu. Scroll down until you see a section labeled IP settings. Your IPv4 address is the number listed there — it will look something like 192.168.1.105. This is the address your router assigned to your Windows device.

If you need more detail, you can also right-click the network icon in your taskbar (bottom right corner), select Open Network & Internet settings, then follow the same path to Status. Both methods show the same information.

Finding your IP address on Mac

Click the Apple menu in the top-left corner and select System Settings (or System Preferences on older macOS versions). Click Network in the sidebar.

Select the connection you're using — usually Wi-Fi if you're on wireless, or Ethernet if you're plugged in with a cable. On the right side of the window, you'll see your connection details. Look for the line labeled IP Address — that's the number you need, usually starting with 192.168.

If you don't see the IP address displayed, click the Details button or Advanced button (depending on your macOS version) to expand the full network information.

Finding your IP address on iPhone or iPad

Open the Settings app and tap Wi-Fi. You'll see a list of networks. Tap the name of the network you're currently connected to — it will have a checkmark next to it.

A details screen appears. Scroll down to find the IP Address field. The number shown there is your device's local IP address on your home network. It typically starts with 192.168 or 10.0.

If you need to see more technical details like your subnet mask or router address, they're also listed on this same screen below the IP address.

Finding your IP address on Android

Open Settings and go to Wi-Fi (or Network & Internet depending on your Android version). You'll see a list of available networks. Find the network you're connected to — it usually has a checkmark or "Connected" label.

Long-press on the network name. A menu appears with several options. Tap Modify or Manage (the exact wording varies by manufacturer). A settings screen opens showing your connection details, including your IP address. Write down the number or take a screenshot if you need it later.

On some Android phones, you may need to tap Advanced or Show Advanced Options to see the IP address field. If you still don't see it, try going to Settings > About Phone > Status to find network information there instead.

What to do once you have your IP address

Once you know your device's IP address, you can use it to access your router's settings page. Open a web browser on that device and type your router's address into the address bar — usually 192.168.1.1 or 192.168.0.1. Your router's manual or the sticker on the back of the device will tell you the exact address if these don't work.

You might also need your device's IP address to set up port forwarding, configure a static IP so the address doesn't change, or troubleshoot why a device isn't connecting to your network. Some people write down the IP addresses of their important devices (like a printer or security camera) so they can find them quickly later.

Keep in mind that these local IP addresses can change over time — your router might assign a different one the next time your device connects. If you need an address to stay the same, you can usually set a static IP or reserved IP in your router's settings, but that's a separate step beyond just finding the address.

Frequently Asked Questions

Why does my IP address look different from what I see online?

Your device actually has two IP addresses. The local one (192.168.x.x) only works inside your home network. Your public IP address is what websites see when you visit them, and you can find it by searching "what is my IP" in any browser. They're different by design — your router translates between them.

Will my IP address change if I restart my device?

Usually not. Your router remembers which device is which and tends to give the same address back. However, if your device is unplugged for a long time or your router restarts, the address might change. If you need it to stay the same, ask your router to reserve that IP address for that device.

Can I find someone else's device IP address on my network?

Yes, by logging into your router's settings page. Most routers show a list of connected devices and their IP addresses. This is useful if you want to see what's connected to your network or if you need to troubleshoot a device that isn't responding.

What if I can't find the IP address in the places you described?

Make sure you're looking in the right section — Settings > Network for most devices. If the field is blank or missing, your device may not be connected to the network yet. Try disconnecting and reconnecting to Wi-Fi, then check again. If it still doesn't appear, restart the device.

Do I need my IP address to find my network?

Not always, but it helps. You need it to access your router's settings page, where you change your Wi-Fi password and update security settings. If you're just connecting devices normally, you don't need to know the IP address — your router handles everything automatically.
