What your internet address is and why you need it

Your internet address — also called your IP address — is a set of numbers that identifies your device on the network, like a mailing address for data. It looks like four numbers separated by dots: 192.168.1.5. When you set up a find home network, you sometimes need this number to log into your router, change settings, or troubleshoot why a device won't connect.

Every device on your network has its own internet address. Your phone has one. Your laptop has one. Your smart TV has one. They're assigned automatically by your router when the device connects, so you don't usually have to think about them — but when something breaks, knowing where to find yours saves you a support call.

Key Takeaways

  • Your internet address is a four-part number your router assigns to each device automatically when it connects to your network.
  • On Windows, open Command Prompt and type ipconfig to see your address listed as "IPv4 Address".
  • On Mac, go to System Settings, click Network, select your connection, and look for "IP Address" in the details.
  • On phones and tablets, the address appears in Settings under Wi-Fi or Network, next to the network name you're connected to.
  • If a device shows an address starting with 169, it failed to connect properly — restart the device and your router.

Finding your internet address on Windows

Open the Start menu and type Command Prompt. Click the Command Prompt app to open a black window with white text. Type the word ipconfig (all lowercase) and press Enter. A list of information appears.

Look for the section labeled with your connection type — usually Ethernet adapter if you plugged in 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 internet address. It will look something like 192.168.1.42 or 10.0.0.15. Write it down if you need it for troubleshooting.

If you see an address that starts with 169 (like 169.254.x.x), your device did not connect to the router properly. Restart your computer and your router, wait two minutes, and run ipconfig again.

Finding your internet address on Mac

Click the Apple menu in the top-left corner and select System Settings. On the left side, click Network. You'll see a list of connection types on the left — click the one you're using, either Wi-Fi or Ethernet.

On the right side of the window, look for a button or link that says Details or Advanced. Click it. A new panel opens. Look for the line labeled IP Address. The number next to it is your internet address. If you don't see a Details button, the IP address may appear directly on the main Network screen.

If the address starts with 169, disconnect from the network and reconnect. On Wi-Fi, click the Wi-Fi icon in the menu bar, select your network name, and enter your password again. On Ethernet, unplug the cable for ten seconds and plug it back in.

Finding your internet address on iPhone or iPad

Open Settings and tap Wi-Fi. Find the network name you're connected to — it will have a checkmark next to it. Tap the information icon (a small circle with an "i" inside) next to the network name. A details screen appears.

Scroll down to find IP Address. The number next to it is your internet address. This is the address your phone uses on your home network. If you need to troubleshoot a connection problem, this is what you'll give to support or use to log into your router settings.

Finding your internet address on Android

Open Settings and tap Network and Internet or Connections (the exact name varies by phone maker). Tap Wi-Fi. Find the network you're connected to and tap it — do not tap "Connect", tap the network name itself.

A details screen appears. Look for IP Address or IPv4 Address. The number shown is your internet address. On some Android phones, you may need to tap Advanced or More details to see the IP address section.

What to do if your address looks wrong

A normal internet address on a home network starts with 192.168, 10.0, or 172.16. If yours starts with something else — especially 169 — your device did not connect properly to the router. This usually means the router didn't assign an address, which happens when the connection drops or the router is overloaded.

Restart the device first. If that doesn't fix it, restart your router: unplug it for 30 seconds, plug it back in, and wait for all the lights to stop blinking. Then reconnect the device to Wi-Fi or Ethernet. Check the address again after two minutes. If it still starts with 169, move closer to the router (if on Wi-Fi) or check that the cable is fully plugged in (if on Ethernet).

Why your address changes sometimes

Your router assigns a new internet address every time a device connects, and the address can change if the device disconnects and reconnects. This is normal and expected. If you need a device to keep the same address — for example, to set up port forwarding on your router — you can assign a static IP address in your router settings, but that's a separate step beyond finding your current address.

For most home network troubleshooting, you just need to know what your address is right now. Write it down while you're looking at it, because it may be different the next time you check.

Frequently Asked Questions

Is my internet address the same as my Wi-Fi password?

No. Your internet address is assigned by the router to each device. Your Wi-Fi password is what you type to connect to the network in the first place. You need the password to join the network; you need the address to troubleshoot once you're connected.

Can someone use my internet address to hack me?

An internet address on your home network is only visible to devices already connected to your router. It's not a security risk by itself. Your real security comes from your Wi-Fi password and your router's firewall, which you set up when you secured your network.

What if I see two different addresses on the same device?

Devices sometimes have both a Wi-Fi address and an Ethernet address if they're plugged in and also connected to Wi-Fi. The device uses whichever connection is active. Check which one you're actually using — if you're on Wi-Fi, ignore the Ethernet address.

Do I need to write down my internet address?

Only if you're troubleshooting a specific problem or setting up port forwarding. For everyday use, you don't need to remember it. Your router handles addresses automatically, and you can look it up again anytime using the steps above.
