Finding the IP address your device is using right now

The fastest way to find your device's IP address depends on what you are using. On Windows, open the Command Prompt (search for "cmd" in the Start menu), type ipconfig, and press Enter. Look for the line that says "IPv4 Address" — that is the number your device uses on your home network. On Mac, open System Preferences, click Network, select your connection, and the IP address appears in the window. On an iPhone or iPad, go to Settings, tap Wi-Fi, select the network you are connected to, and scroll down to see the IP address listed there.

On Android phones, the process is slightly different because Android does not show this information as directly. Go to Settings, tap About Phone, then tap Status or Network. Some Android versions label it differently, so if you do not see it in those spots, search "IP address" within Settings. Linux users can open a terminal and type hostname -I to see the address when ready.

The number you find will look something like 192.168.1.5 or 10.0.0.3 — three sets of numbers separated by periods. This is your device's local IP address, the one it uses only within your home network. It is different from your public IP address, which is what websites see when you visit them.

Key Takeaways

  • Windows users can find their local IP address by opening Command Prompt and typing ipconfig, then looking for the IPv4 Address line.
  • Mac users find the IP address in System Preferences under Network, and iPhone users find it in Settings under Wi-Fi details.
  • Your local IP address (like 192.168.1.5) is different from your public IP address and only works within your home network.
  • If you need to find another device's IP address on your network, you can check your router's connected devices list or use a network scanning tool.

Finding another device's IP address on your home network

If you need to know the IP address of a different device — a printer, another computer, a smart TV — the easiest method is to check your router's list of connected devices. Log into your router by opening a web browser and typing the router's address (usually 192.168.1.1 or 192.168.0.1, printed on the router itself). Enter your router's username and password, then look for a section called "Connected Devices," "Device List," or "DHCP Clients." Every device currently on your network will be listed with its IP address.

If you cannot access the router or prefer not to, you can find the IP address directly on the device itself using the same steps listed above. For example, if you want your printer's IP address, go to the printer's settings menu (usually through buttons on the printer or through its own app) and look for Network Settings or Device Information. Smart devices like speakers or cameras often have their own apps where you can see the IP address in settings.

On Windows, you can also use a tool called Command Prompt to scan your network. Type arp -a to see a list of all devices that have recently communicated with your computer, along with their IP addresses. This method is less reliable than checking the router because it only shows devices your computer has talked to recently, not all devices on the network.

Understanding what the numbers mean

An IP address is four numbers separated by periods, and each number can range from 0 to 255. Your home network almost always uses addresses that start with 192.168 or 10.0 — these are reserved ranges that routers use for local networks. The last one or two numbers are what change from device to device. So if your computer is 192.168.1.5, your phone might be 192.168.1.12, and your printer might be 192.168.1.20.

The reason these numbers matter is that they let devices on your network find each other. When you print something, your computer sends the job to the printer's IP address. When you stream video to a smart TV, your phone sends the stream to the TV's IP address. Without these addresses, your devices would not know where to send information.

Some devices get a new IP address every time they connect to the network (called a dynamic address), while others keep the same one (called a static address). Most home devices use dynamic addresses, which is why a device's IP address might change if you restart your router or if the device has been offline for a while. If you need a device to always have the same address — like a printer or a server — you can set a static IP address in your router settings, but that is a more advanced step.

Finding your public IP address

Your public IP address is what the outside internet sees when you visit a website. It is assigned by your internet service provider and is different from your local IP address. To find it, open any web browser and search for "what is my IP address" or visit a site like whatismyipaddress.com. The page will display your public IP address when ready — it looks the same as a local address (four numbers separated by periods) but is a completely different number.

Your public IP address changes periodically, usually when your router restarts or when your internet service provider updates its systems. Unlike your local IP address, you do not need to know your public IP address for everyday use. It becomes relevant only if you are setting up remote access to your home network, running a server, or troubleshooting internet connectivity issues with your provider.

When you might need to look up an IP address

The most common reason to look up an IP address is to connect to a device on your network that is not showing up normally. If a printer stops responding, you can use its IP address to access its settings page directly through a web browser. If a smart home device is not responding to voice commands, you can sometimes restart it by accessing its IP address. If you are troubleshooting a slow network, you might need to see which devices are connected and using bandwidth.

Another reason is to set up port forwarding or remote access. If you want to access your home computer from outside your house, you need to know both your local IP address (for the computer you are accessing) and your public IP address (to reach your home network from the internet). Network administrators and people who run home servers use IP addresses regularly, but for most people, looking up an IP address is something you do once or twice when something is not working right.

Troubleshooting when you cannot find an IP address

If you look for an IP address and the device does not show one, the device is probably not connected to the network. Check that the device is turned on and that it is connected to your Wi-Fi (or plugged in with an ethernet cable if it uses a wired connection). Wait a minute or two — some devices take time to connect and receive an IP address from the router. Then try looking again.

If a device is connected but still does not show an IP address, try restarting the device. Power it off completely, wait 10 seconds, and turn it back on. Once it reconnects to the network, it should receive an IP address. If that does not work, restart your router by unplugging it for 30 seconds, plugging it back in, and waiting for all the lights to stabilize before trying again.

If you are trying to access a device's settings page using its IP address and it is not loading, make sure you are typing the address correctly and that the device is actually on the network. Try typing http:// before the IP address (for example, http://192.168.1.100) rather than just the numbers alone. If the page still does not load, the device may not have a web interface, or it may require a different method to access its settings.

Frequently Asked Questions

Is my IP address the same as my MAC address?

No. Your IP address is the number your device uses to communicate on the network (like 192.168.1.5). Your MAC address is a unique identifier built into your device's network hardware and looks like six pairs of letters and numbers (like 00:1A:2B:3C:4D:5E). Both are useful for different reasons, but they are completely separate.

Can someone hack me if they know my IP address?

Your local IP address (the one on your home network) is only visible to other devices on your network, so knowing it does not create a security risk. Your public IP address is visible to websites you visit, but it only tells someone your general location and internet provider — it does not let them access your computer or personal information directly. Standard security practices like firewalls and strong passwords protect you far more than keeping your IP address secret.

Why does my device's IP address keep changing?

Most home networks use dynamic IP addresses, which means the router assigns a new address each time a device connects. This is normal and not a problem. If you need a device to always have the same IP address, you can set a static IP address in your router settings, but this is usually only necessary for printers, servers, or devices you access frequently by their IP address.

How do I find the IP address of a device that is not on my network right now?

You cannot see the IP address of a device that is not connected to your network. Once a device disconnects, it no longer has an active IP address on your network. If you need to find it later, you would have to wait for it to reconnect, then check the router's device list or the device itself.
