How does reverse DNS work?
Reverse DNS turns an IP address into a name. How the PTR record works, who controls it and why mail servers care.
What is my IP address?

Finland's internet
How much address space is registered in Finland, which Finnish networks announce the most of it, and how many of their routes are protected by RPKI — recomputed every time our datasets are rebuilt.

We compile the data ourselves from public sources: routing and registries daily, location every few days. Missing data is shown as missing.
We don't log visitor IP addresses or set tracking cookies. Every lookup runs against our own data, on our own server.
IP geolocation is an estimate. We show the source of each field and never imply precision we don't have.

No IPv6 address, IPv6 that exists but doesn't work, or sites that load slowly: a checklist from your device to your provider.
The fastest way, and how to find both your public and your private address on Windows, macOS, iPhone, Android and your router.
It is the address your connection uses on the internet. Every website you visit sees it. At home it usually belongs to your router, which shares it between all your devices.
IP location is an estimate of where an address block is used, often where the provider's equipment is. It is usually right about the country and often wrong about the city. It cannot locate a person or a street address.
Your internet provider, your router or the network you are on doesn't offer IPv6, or it is switched off. Websites then reach you over IPv4 only, which still works normally.
Many home and mobile connections get a new address now and then, for example when the router restarts. Some subscriptions include a fixed address.
Not from the address alone. It shows the network and an approximate area. Only your internet provider can link an address to a subscriber, and only shares that under legal process.
No. Your device's address on the home network (often 192.168.x.x or 10.x.x.x) is private and is not visible on the internet. This page shows the public address.
Marker shows the estimated centre of the area; the circle indicates uncertainty. Never use IP location to find a person or a street address.
