My Connection Report
Everything the edge can see about your connection, on one page.
Where this comes from
A single request to a Cloudflare Pages Function returns what the edge already knows about the connection that made it — the address, the network operator and its ASN, the approximate location that address is registered to, the protocol and TLS version negotiated, and the round-trip time measured during the TCP handshake. None of it required a permission prompt, because none of it is read from your device: it is a property of the connection itself, and every site you visit can see the same.
What the results mean
- ASN and network operator
- The autonomous system your address belongs to — your ISP, your mobile network, or a VPN provider if you are using one.
- Cloudflare edge
- The data centre that answered, identified by airport code. It is usually the nearest one with capacity, which is a rough hint at your region.
- TCP round trip
- Measured during the handshake, so it excludes the server's handling time. It is the closest thing here to a true network latency, and only to that edge.
- Approximate location
- Derived from the address registration, not from your device. City-level at best, and frequently the wrong city on mobile networks.
Common problems and fixes
- The location is wrong
- It is where the address block is registered rather than where you are. Mobile networks in particular route traffic through a handful of gateways, which can be hundreds of miles from the handset.
- The network operator is not my ISP
- Check whether a VPN, a corporate network or a mobile carrier gateway is in the path — the operator shown is whoever owns the address the request arrived from.
- HTTP/3 is not being used
- Not a fault. The browser negotiates the version, and some networks and middleboxes block the transport HTTP/3 depends on, so it falls back.
Frequently asked questions
What can a website tell about me without permission?
This page is the answer: your IP address, the network that owns it, the approximate location it is registered to, and the technical properties of the connection. Every site you visit sees all of it, and none of it prompts you. Anything more specific — your camera, your location, your clipboard — requires a permission you would be asked for.
How accurate is IP location?
Country is usually right. City is often right for fixed lines and frequently wrong on mobile, where traffic surfaces at a regional gateway. Street-level accuracy from an IP address is not a thing, whatever a lookup site displays.
Is any of this stored?
No. The endpoint reads the connection properties, returns them, and marks the response private and no-store so it cannot be cached. Nothing is written down.
