How to Find the IP Address of Any Device on Your Network With an iPhone

You need an IP address. Maybe a printer setup asks for it, a camera app wants it, or you want to open your router's settings page. Your iPhone shows its own address, deep in the Wi-Fi settings, but not anybody else's. In this video we find the address of every device on the network, the router's address, and the public one your internet provider gives you.

We use DeviceShelf for iPhone with its demo network, a made-up home called Homebase. The addresses you see are fictional. Yours will look similar, usually starting with one ninety two dot one sixty eight.

First, a quick look at the iPhone's own address, because you'll need it to make sense of the rest. In the iPhone's Settings, tap Wi-Fi, then the small i next to your network. There you'll find the IP address, the subnet mask and the router. That's all the phone tells you about the network.

DeviceShelf goes further. It scans every address in your network and lists everyone who answers. The header shows the network range, here one ninety two dot one sixty eight dot one dot zero slash twenty four. That means all addresses from dot one to dot two fifty four, and the scan went through all of them.

Each row shows one device with its IP address on the right. The DiskStation is at dot twenty, the HP printer at dot thirty, the Apple TV at dot sixty. Scroll down and you see the rest of the house.

The list is sorted by IP address, which puts it in the same order as the addresses themselves. That's handy when you're looking for a free address or checking a range. The sort button offers two other orders.

By response time puts the quickest devices first, the ones on a cable or close to the router. By IP brings back the address order, with the router at dot one on top.

When you know what you're looking for, search for it. Names, vendors and types all count. Type HP, and there's the printer, at one ninety two dot one sixty eight dot one dot thirty. That's the address the printer setup on your computer asks for.

It also works the other way round. Some app shows you an address and you want to know whose it is. Type the end of it, dot eighty, and you get the Reolink camera.

Tap the device for everything that belongs to its address: the hardware address, called the MAC, the hostname, the response time and the open ports. For a camera, port five fifty four is the video stream, the address your recording software needs.

One more thing you'll find here: the Web UI button. If a device has a web page, it opens right in the browser, so you don't have to type the address at all.

A word about addresses that change. Most devices get their address from the router, and the router can hand out a different one after a restart. If a device keeps moving, give it a fixed address in the router, called a DHCP reservation. Then the address you look up today is still right next month.

Next, the router. Its address is the gateway, the door from your home network to the internet. In the list, it's the row with the gateway badge. Here that's the Fritz box at one ninety two dot one sixty eight dot one dot one, which is the most common router address. Others use dot zero dot one, or ten dot zero dot zero dot one.

Open it, and you see the same details as for any device. Port eighty and four forty three mean the router has its settings page there. Type the address into Safari and you get the router's login, or tap Web UI right here.

That page is where you block devices, reserve addresses and change the Wi-Fi password. Keep the router's address somewhere you'll find it again.

There's a third address people mean when they say my IP: the public one. All devices at home share it on the internet. Your provider assigns it, and websites see it. You find it on the Diagnostics tab.

Under Internet and ISP, tap Run. The app asks Cloudflare which address your connection comes from, and looks up the provider and the rough location that belong to it. In the demo you see a sample address, two oh three dot zero dot one thirteen dot forty two, from a range reserved for examples.

That's the address you'd give someone who needs to reach your network from outside, or the one you check when a service says you're connecting from an unexpected place. Many home connections get a new public address from time to time, so it's worth checking again rather than writing it down.

To sum up. Your own address is in the iPhone's Wi-Fi settings. Every other device's address is in DeviceShelf's list: search by name to find an address, or by address to find the device. The router is the row with the gateway badge. And the public address is under Diagnostics, Internet and ISP. DeviceShelf for iPhone is in the App Store, and the link is in the description.
