An IP address (Internet Protocol address) is a unique numerical label assigned to every device connected to the internet. Think of it as your device's home address on the internet - it allows data to find its way to you and back.
How IP Addresses Work
When you connect to the internet, your Internet Service Provider (ISP) assigns an IP address to your router. This address is used to identify your connection and route data packets to and from your device.
Every website you visit can see your IP address. This is necessary for the internet to function - websites need to know where to send the data you request. However, this also means your IP reveals information about you.
IPv4 vs IPv6
There are two types of IP addresses in use today:
- IPv4 - The original format, consisting of four numbers separated by dots (e.g., 192.168.1.1). There are about 4.3 billion possible IPv4 addresses.
- IPv6 - The newer format, created because we're running out of IPv4 addresses. IPv6 uses eight groups of four hexadecimal digits (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
Public vs Private IP Addresses
Your public IP address is assigned by your ISP and is visible to the entire internet. This is what websites see when you visit them, and what our tool shows you.
Your private IP address is used within your local network (like 192.168.x.x). Devices on your home network use private IPs to communicate with each other, but these are not visible to the outside world.
What Your IP Address Reveals
Your IP address can reveal:
- Your approximate geographic location (city and region)
- Your Internet Service Provider (ISP)
- Your connection type (residential, business, mobile)
However, an IP address alone cannot reveal your exact home address, your name, or other personal details.
Why IP Addresses Matter for Privacy
Websites and online services can use your IP address to:
- Track your browsing activity across sessions
- Block or allow access based on your location
- Customize content for your region
- Enforce regional restrictions on content
If you're concerned about privacy, you can hide your IP address using a VPN (Virtual Private Network), which masks your real IP with the VPN server's address.
