What Is My IPv4 Address? How to Find It on Any Device

Your IPv4 address is the number your device uses to talk to the internet. If you're trying to find yours right now, here's the short version: your public IPv4 address shows up automatically the moment you visit iptrackertools.com/what-is-my-ip. No typing, no signup.

If you want to know what that number actually means, or how to find it on a specific phone or computer, keep reading. This guide covers all of it.

What IPv4 Actually Means

IPv4 stands for Internet Protocol version 4. It's the numbering system that gives every device online an address, the same way a street address tells the postal service where to deliver a letter.

An IPv4 address is written as four numbers separated by dots, like this:

203.0.113.45

Each of those four numbers can be anywhere from 0 to 255. That format has been the backbone of internet traffic since the early 1980s, and it still handles most of the world's connections today.

You might also hear the term "IPv4 internet address" or just "IP number." They all mean the same thing.

What Does My IPv4 Address Look Like?

If your address is written with dots between plain numbers, like 192.168.1.1 or 8.8.8.8, that's IPv4.

If you see something long with letters and colons, like 2001:0db8:85a3::8a2e:0370:7334, that's IPv6 — a newer, different system. This guide focuses on IPv4 only.

How to Find Your IPv4 Address Right Now

The fastest way to check your address, on any device, is to open a browser and go to iptrackertools.com/what-is-my-ip. The tool reads your connection and shows your public IPv4 address on the page instantly.

This works the same way whether you're on a laptop, a phone, or a tablet, because the browser is doing the work — not your operating system.

That number is your public IPv4 address, the one websites and servers see when you connect. If you need your private address instead — the one your router assigns to your device on your home network — you'll need to check your device settings, covered below.

Finding Your IPv4 Address by Device

On a Windows PC

1. Press the Windows key and R at the same time.
2. Type cmd and hit Enter to open Command Prompt.
3. Type ipconfig and press Enter.
4. Look for "IPv4 Address" under your Wi-Fi or Ethernet adapter.

That number, something like 192.168.1.14, is your private IPv4 address on your local network.

On a Mac

1. Click the Apple menu, then System Settings (or System Preferences on older versions).
2. Click Network.
3. Select your active Wi-Fi or Ethernet connection.
4. Your IPv4 address is listed right there in the details panel.

On an Android Phone

People searching "what is ipv4 on my android" usually just want this:

1. Open Settings.
2. Tap About Phone, then Status (the exact wording depends on your phone brand).
3. Look for "IP Address."

Some Android versions show it under Settings → Wi-Fi → tap your connected network → Advanced.

On an iPhone or iPad

1. Open Settings.
2. Tap Wi-Fi.
3. Tap the blue (i) icon next to the network you're connected to.
4. Your IP Address is listed under the DHCP section.

On a Router (to see connected devices)

Log into your router's admin page, usually at 192.168.1.1 or 192.168.0.1, and look for a "connected devices" or "DHCP clients" list. This shows the private IPv4 address assigned to every device on your network, not just your own.

Public vs. Private IPv4: Why the Numbers Are Different

This is where most confusion starts, including questions like "aren't his and my IPv4 the same?"

You actually have two IPv4 addresses at once:

• Public IPv4 — assigned by your internet provider. This is what a website sees when you visit it. Every device on the same home Wi-Fi shares this exact number.
• Private IPv4 — assigned by your router to each device individually. Your laptop, phone, and smart TV all get different private addresses, even on the same network.

So if you and someone else are on the same Wi-Fi and both check "what is my IPv4 address" on a website, you'll see the same number. That's expected. But check your phone's Wi-Fi settings, and your private address will be different from theirs.

Outside your home network, on mobile data or a different Wi-Fi, your public IPv4 will usually be different from anyone else's, since it depends on your provider and location.

Why the Same IPv4 Number Can Show Up on Different Days

Most home internet plans don't give you a permanent IPv4 address. Providers rotate addresses among customers to stretch a limited supply, so your public IPv4 might change every time you restart your router, or after a few days.

This is normal and isn't a sign of a problem. If you need an address that never changes, that's called a static IP, and it's usually a paid add-on from your provider.

When You Actually Need Your IPv4 Address

Most people look this up for one of these reasons:

• Setting up port forwarding for gaming or a home server
• Allowing a specific IP through a firewall
• Whitelisting your address for remote access to a database or server
• Confirming a VPN changed your address correctly
• Troubleshooting a connection issue with your internet provider

For anything involving your router (port forwarding, device whitelisting), use your private IPv4 from the device steps above. For anything involving the wider internet (VPN checks, server whitelisting), use your public IPv4 from the lookup tool.

Quick Answers

What is an IPv4 address, in plain terms? It's the number that identifies your device on the internet, similar to a phone number for your connection.

How do I find my IPv4 address without downloading anything? Visit iptrackertools.com/what-is-my-ip in any browser. It shows up automatically.

Is my IPv4 address the same as my Wi-Fi password? No. Your IPv4 address identifies your connection. It has nothing to do with your network password and isn't a security credential on its own.

Can two people have the same IPv4 address? Yes, if they're on the same home or office Wi-Fi, their public IPv4 address will match. Their private addresses, assigned to each device, will still be different.

Does my IPv4 address reveal my exact home address? No. It can point to your general city or region through your provider, but it doesn't show a street address.

The Short Version

Your public IPv4 address is visible the moment you check iptrackertools.com/what-is-my-ip. Your private IPv4 address lives in your device's network settings, and the steps differ slightly by device but only take a minute either way. Knowing the difference between the two clears up almost every point of confusion people run into with IPv4.
