What Is My IP
Your public IP address and what the connection reveals with it — country, the Cloudflare data centre answering you, protocol version, encrypted-DNS status. One request to Cloudflare's trace endpoint when you press the button; nothing runs before you ask, and nothing is stored.
The one tool here that must ask the network
Everything else on this site computes in your tab. This page cannot: a machine does not know its own public address, because that address is assigned outside it — by NAT, by the provider, by a VPN. The only way to learn it is to ask someone on the outside what they see, and this page asks exactly once, on your click, to one endpoint.
The rest of the rows are the connection's own metadata: HTTP version tells you whether you speak modern multiplexed protocols, TLS names the encryption generation, and the WARP flag shows whether Cloudflare's own VPN wraps your traffic.
Frequently asked questions
Why does my IP differ from what my router shows?
The router shows the private address of your LAN — 192.168.x.x or 10.x.x.x — which never leaves the building. The address here is the public one your provider NATs you behind, the one websites actually see. Entire buildings routinely share one.
How does this page know my IP without me typing it?
Every request you make carries your address by necessity — it is the return envelope. The trace endpoint simply reads it off the connection and echoes it back. That is also why the page waits for your click: knowing your IP requires making a request, so the request is yours to make.
What does the 'answered by' airport code mean?
Cloudflare names its data centres by the nearest airport — FRA is Frankfurt, IST Istanbul. It is where your packets surfaced into their network, which is usually the closest point to you, and a decent proxy for how your traffic routes.
Is my location really visible from my IP?
To country level, reliably; to city level, roughly; to street level, not at all — IP geolocation maps addresses to provider registrations, not to homes. A VPN or WARP replaces the visible address entirely, which is exactly what the WARP row detects.
