What it does

Questions people ask

1. What is ipapi.is?

   ipapi.is is a fast and accurate IP address API that retrieves metadata for any IPv4 or IPv6 address on the Internet. Clients use it for blocking malicious traffic (from datacenters, Tor, proxies, VPNs), traffic classification, and IP geolocation intelligence for targeted advertising or location-based actions.

2. Is the API stable and how many servers are behind ipapi.is?

   The API is hosted in three geographical locations: US East, Central Europe (Germany), and Singapore/Asia. Each API server can handle 1,000 requests per second. The platform uses Microsoft Azure Cloud DNS and Azure Traffic Manager to route requests to the geographically closest server, reducing latency for end-users.

3. How often is the API data updated?

   The core API data is updated every week. Fast-moving data, such as VPN exit nodes and abuser intelligence, is updated daily.

4. Can I self-host the ipapi.is API?

   Yes. The Business subscription ($200/month) allows you to run the complete ipapi.is API in your own infrastructure. The self-hosted server ships as a single native Linux binary with no runtime dependencies, requires only 4 GB of RAM, and handles more than 100,000 lookups per second on four-core hardware. Self-hosted lookups are unlimited with daily database updates and zero-downtime swaps.

5. How fast is the API?

   On average, a simple IP lookup takes 1.02 milliseconds of processing time on the API servers. The self-hosted API server handles more than 100,000 lookups per second on four-core hardware without any network round trip.
