FAQ
What is an IP address?
An IP address is a numerical label assigned to every device connected to a network. It's how devices find and communicate with each other over the internet, similar to a postal address for data.
What's the difference between IPv4 and IPv6?
IPv4 addresses are the older, shorter format (e.g. 203.0.113.42) and the pool of available addresses is nearly exhausted. IPv6 addresses are longer (e.g. 2001:db8::1) and were introduced to provide a vastly larger address space. Most devices today use both.
Is my IP address the same as my location?
Not exactly. Your IP address can be used to estimate your general location — usually your city or region — based on which internet provider assigned it to you, but it's rarely precise enough to pinpoint your exact address.
Can someone track me using my IP address?
An IP address alone typically reveals your approximate location and ISP, not your identity or exact address. That said, it can be logged by websites you visit, so many people use a VPN if they want to mask it.
Why does my IP address change?
Most home internet connections use a 'dynamic' IP address that your ISP can change periodically, for example when you restart your router. Connecting to a different network (like a coffee shop's WiFi or mobile data) will also give you a different IP.
