What is a public IP address?
A public IP address is a numerical identifier that makes your device visible on the internet. Your internet provider (ISP) assigns it, and it is used in communication with servers - every website you visit sees this IP of yours. Local IP addresses (like 192.168.x.x or 10.x.x.x) are internal only and the public internet does not see them.
IPv4 vs IPv6 - what is the difference?
IPv4 (e.g. 89.221.213.14) is the older 32-bit format that allows about 4.3 billion addresses - not enough today. IPv6 (e.g. 2a00:1450:400b:803::200e) is 128-bit and provides a practically unlimited number of addresses. Most EU ISPs support both protocols today, but IPv4 still dominates. Our tool shows you the one your browser used for this connection.
Why does my IP change?
Home IPs are usually dynamic - the ISP assigns them temporarily and they change after a router restart or at a set interval. You usually have a static (unchanging) IP only at work, on a server, or if you pay your ISP for it. The IP also changes when switching to mobile data, using a VPN, or connecting to public Wi-Fi.
Is showing my IP private?
Yes. Our interface does not store your IP in any database, does not use tracking cookies, does not pass data to third parties. We detect the country via a local offline database (dbip.com Lite, no external calls). ISP and city info come via public ipinfo.io in real time, without storage.
