What is my IP address, and why can this site see it?
The dossier above shows your public IP address: the number your internet service provider assigned to your connection so that machines elsewhere on the internet can route data back to you. It works like the return address on an envelope. Every website you visit sees it, because without it the site's reply would have nowhere to go. This page simply reads the address from your own request and runs it through the same tracer you can point at any other address.
Visible by design
Your IP is not being leaked — it is a required part of how the internet's routing protocols work. What varies is how much can be inferred from it, and that is what the dossier estimates. Note that every device on your home network shares one public address; individual phones and laptops behind your router are indistinguishable from the outside.
IPv4 or IPv6, dynamic or static
You may see one of two formats. IPv4 addresses are four numbers separated by dots, such as 203.0.113.7; the global pool is essentially exhausted, so providers recycle them constantly. IPv6 addresses are longer hexadecimal strings, plentiful enough that a network can give every device its own. Many connections carry both — the differences are covered in IPv4 vs IPv6. Most residential addresses are dynamic: the provider leases you an address and may rotate it when your router reconnects. A static address never changes and is usually a paid business feature.
Reading the dossier fields
| Field | What it means |
|---|---|
| ASN | The autonomous system announcing your address — in practice, which network you reach the internet through. See what an ASN is. |
| Registrant | The organization recorded for this address block in the public registries run by the regional internet registries, such as ARIN and RIPE NCC. |
| Connection class | A heuristic reading of the operator's name: residential broadband, mobile carrier, or a LIKELY datacenter/VPN flag. An informed guess, never proof. |
| Confidence | How far the geolocation estimate can be trusted, derived from DB-IP Lite data. |
What your IP does not reveal
An IP address identifies a network attachment point, not a person. It carries no name, no street address, and no way to tell members of a household apart. Geolocation places it only in a probable area: country-level estimates are reliable at roughly 95–99%, while city-level is right perhaps half to three-quarters of the time on fixed broadband and frequently wrong on mobile, VPN, or satellite connections — the full picture is in how accurate IP geolocation is. If your concern is privacy, read can someone find my address from my IP. The short answer is no.
