What Is an IP Address?
An IP address (Internet Protocol address) is a unique number assigned to every device connected to the internet. Think of it as your digital mailing address. Every website you visit, every email you send, and every video you stream uses your IP address to route data back to your device.

IPv4 vs IPv6
There are two types of IP addresses in use today. IPv4 addresses look like 192.168.1.1 (four numbers separated by dots). IPv6 addresses are longer, like 2001:0db8:85a3::8a2e:0370:7334. IPv6 was created because the world ran out of IPv4 addresses. Most devices now support both. Learn more in our IPv4 vs IPv6 guide.
What Your IP Address Reveals
Your IP address tells websites more than you might expect:

Your connection type — residential, business, VPN, or datacenter

How to Protect Your IP Address
The most effective way to hide your IP is to use a VPN (Virtual Private Network). A VPN replaces your real IP with the VPN server's IP, making it much harder to track you. After connecting to a VPN, verify it is working with our DNS leak test and WebRTC leak test.
For a comprehensive privacy assessment, run our Privacy Checkup to get a grade from A+ to F based on your IP exposure, VPN status, browser fingerprint, and more.
