Shows your public IP address, location, internet provider, and whether a VPN/proxy connection was detected.
Here we answer the most important questions about IP addresses and our free IP Check tool.
An IP address is a unique number assigned to every device on the internet – comparable to a postal address. It allows servers and other devices to deliver data packets to the right destination, and is a basic requirement for any internet connection.
If you use a VPN service or proxy server, your traffic is routed through an intermediary server. Our tool analyzes typical technical characteristics of such connections and transparently shows you whether masking of your real IP address was detected.
IPv4 is the older standard with a limited address space that is becoming increasingly scarce worldwide. IPv6 solves this problem with a significantly larger address space and is being used by more and more internet providers and servers alongside or instead of IPv4.
