How To Find Your Ip Address On Windows And Mac

Finding your computer's IP address takes less than a minute once you know where to look. Whether you're troubleshooting a dropped connection, setting up a printer, or configuring local file sharing, your device needs an Internet Protocol address to communicate with other hardware.

Every device connected to a network has two distinct types of addresses: a private local address used within your home or office, and a public address that websites see when you browse the web. Knowing how to locate both gives you the control you need to manage your home network effectively.

Understanding Local Versus Public IP Addresses

Before running any commands, it helps to know what kind of number you're looking for. Your router assigns a local IP address to your computer, phone, and smart TV. These numbers usually start with 192.168. or 10. and only have meaning inside your local network.

Your public IP address is assigned by your internet service provider. Millions of devices share a single public address outside your home router using Network Address Translation. When you visit sites like IETF, they see your public routing identifier rather than your local machine address. If you want more about the history of this, Associated Press provides an excellent breakdown.

How to Find Your IP Address on Windows

Windows provides multiple built-in utilities to check network configurations. The fastest route is using the command line tool, which bypasses cluttered settings menus.

Using Command Prompt

Press the Windows key, type cmd, and press Enter to open the Command Prompt.
Type ipconfig and hit Enter.
Scroll through the text to find your active network connection, labeled as Wireless LAN adapter Wi-Fi or Ethernet adapter.
Look for the line reading IPv4 Address. It will display a string like 192.168.1.50.

If you need deeper details about your network lease time and DNS servers, type ipconfig /all instead. This command lists every physical and virtual adapter on your machine.

Using Windows Settings

If you prefer a graphical interface, you can find your network details through the modern settings app:

Open Windows Settings by pressing Windows Key + I.
Navigate to Network & internet.
Click on Wi-Fi or Ethernet, depending on how you're connected.
Click on your active network connection name to open its properties.
Scroll down to find your IPv4 and IPv6 addresses listed under properties.

How to Find Your IP Address on macOS

Apple keeps network configurations tucked away inside system settings. The layout varies slightly depending on your version of macOS, but the underlying steps remain consistent.

Using System Settings

Click the Apple logo in the top-left corner of your screen and select System Settings.
Click Wi-Fi or Network in the sidebar.
Select your active connection, then click the Details button next to it.
Select TCP/IP from the side menu to view your IPv4 address, subnet mask, and router address.

Using Terminal

If you prefer a faster method on Mac, you can query your network interfaces directly through the terminal:

Open Spotlight by pressing Command + Space, type Terminal, and hit Enter.
Type ipconfig getifaddr en0 for Wi-Fi or ipconfig getifaddr en1 for Ethernet, then press Enter.
Your active local IP address will print directly onto the screen.

How to Find Your Public IP Address

Your local address won't help when you're trying to configure port forwarding for a game server or remote desktop connection from outside your home. For those tasks, you need your public routing address.

You don't need a command line tool for this. You can simply ask any external web server what your browser looks like from the outside. Searching for "what is my IP" on a trusted network utility site will instantly display your public IPv4 and IPv6 numbers. You can also verify your connection details directly through documentation provided by the Internet Society.

Common Network Troubleshooting Mistakes

When users try to find or use their IP addresses, a few common pitfalls often cause confusion. Avoiding these mistakes saves time during network troubleshooting.

Confusing local and public addresses: Giving someone your 192.168.x.x address won't let them connect to your home computer from across the internet because those private blocks aren't routable globally.
Ignoring dynamic changes: Most home routers use DHCP, meaning your computer's local IP address can change after a reboot or when your DHCP lease expires. If you set up static routing rules, always assign a static IP within your router's configuration panel.
Checking the wrong adapter: Modern laptops have Wi-Fi, Ethernet, and Bluetooth network adapters simultaneously. Always verify you're reading the address for the active connection you're currently using.

Frequently Asked Questions

Why does my IP address change?

Most Internet Service Providers and home routers use dynamic IP assignment. When your device disconnects or your router reboots, it releases the address back into a pool and might hand you a different one next time.

Can someone find my physical location using my IP address?

Your IP address reveals the general geographic region and your internet service provider, but it doesn't give away your exact street address or home name. That precise location data remains private with your service provider.

What is the difference between IPv4 and IPv6?

IPv4 uses a 32-bit address scheme that supports about 4.3 billion unique devices, which ran out years ago. IPv6 uses a 128-bit address system, providing a virtually endless supply of unique identifiers to accommodate modern connected hardware.

How do I set a static IP address?

You can configure a static IP address directly through your operating system's network adapter properties, or by setting a DHCP reservation inside your router's admin panel. Setting it at the router level is usually safer because it prevents local IP conflicts on your network.
