See the address the internet sees you as, then inspect any IP: what kind it is, why 192.168.x.x can never be reached from outside, what an IPv6 address expands to, and what its reverse DNS says. Classification runs locally; only your-own-IP and PTR lookups touch our server, and the page says which.
The address the internet sees you as
Asking our server…
Only a server you talk to can know this — it reflects your address back and stores nothing.
Type or paste a public web address. Nothing about your own files or device is involved — only the page you name.
This is one of the few Programs tools that can’t run on your device — browsers deliberately can’t read other websites. Our server fetches the page and sends the result straight back: nothing is stored, and the address is never logged or put into analytics.
The answer appears on this page as you go. There is nothing to download, because the answer IS the page — screenshot it or write down what matters. No copy is kept on our side — there is no storage for one to sit in.
