What is my IP address?

Your IP address is a unique numerical identifier assigned to your device when connected to the internet. It works like your home's postal address, but for the online world. Every device that connects to the internet needs an IP address to send and receive data.

At WhatsMyIP.net, we show you your public IP address—the one visible to websites and online services when you browse the internet.

Why do I need to know my IP address?

Knowing your IP address is useful for several reasons:

• Troubleshooting network connection problems
• Setting up remote connections to your computer
• Configuring home network devices
• Verifying if your VPN is working correctly
• Understanding your digital footprint

What's the difference between IPv4 and IPv6?

IPv4 addresses (like 192.168.1.1) are the original internet protocol and use a 32-bit format. IPv6 addresses (like 2001:0db8:85a3:0000:0000:8a2e:0370:7334) use a newer 128-bit format. IPv6 was created to solve the problem of running out of IPv4 addresses as more devices connect to the internet.

Learn more about these differences in our IP address explanation guide.

Can someone track me with my IP address?

Your IP address can reveal your approximate location (usually city-level) and internet service provider, but not your exact physical address or personal identity. However, it can be used to track your online activities across websites.

How can I hide or change my IP address?

You can hide your real IP address by:

• Using a VPN (Virtual Private Network) service
• Using the Tor browser
• Using a proxy server
• Using public WiFi (although this has security risks)

A VPN is generally the most reliable and user-friendly option for most people seeking privacy online.
