Our global anycast network spans 21 points of presence in key datacenter locations, helping us deliver low-latency API responses, high redundancy, resilient global availability, and up to 100% monthly uptime.
Anycast allows the same API endpoint to be served from multiple global locations at once. When a request reaches our API, it is automatically routed to the nearest or fastest available point of presence. This helps reduce latency for IP geolocation lookups, improves response times for users worldwide, and keeps the API available even if one route or location becomes degraded.
Every point of presence in our network is continuously monitored from 50 global network monitoring points to detect latency, routing issues, and availability problems in real time. If a network path becomes congested or unavailable, traffic can be rerouted automatically to a healthier location. Our team also stays on call around the clock to respond quickly whenever human attention is needed.
Our network operates from 21 datacenters across North America, South America, Europe, the Middle East, Asia-Pacific, and Africa — including Ashburn, New York, Chicago, Dallas, Atlanta, Miami, Los Angeles, Seattle, São Paulo, London, Frankfurt, Milan, Helsinki, Kyiv, Dubai, Mumbai, Singapore, Hong Kong, Tokyo, Sydney, and Johannesburg.
Requests are automatically routed to the closest healthy location, helping keep latency low for users worldwide.
Median response time across our global network is around 50 ms, with most regions seeing well under 100 ms end-to-end. Cached lookups can be served even faster, helping reduce latency for repeated IP geolocation requests.
Actual latency depends on the user's distance to the nearest PoP, routing conditions, and their local network provider.
The network is built with redundant infrastructure across multiple providers and regions. If a PoP, datacenter, route, or upstream provider becomes degraded, traffic can be rerouted to the next healthy location without any client-side changes.
Every point of presence is continuously monitored from 50 global network monitoring points, and an on-call engineer is available 24/7 when a problem requires human attention.
No. IPWHOIS.IO provides separate endpoints for different API plans, but you do not need to choose a region.
Use https://ipwho.is/ for the Free Endpoint and https://ipwhois.pro/ for the Pro Endpoint. Both endpoints use global routing to transparently direct requests to the nearest healthy point of presence, so you do not need to maintain regional URLs, DNS overrides, or failover logic on your side.
Anycast allows the same endpoint to be served from multiple locations around the world. When a request reaches our network, it is routed to the nearest or fastest available point of presence.
For IP geolocation, this reduces the distance each request travels and helps deliver faster responses for websites, applications, and backend services used by global audiences.
Yes. Our infrastructure is designed for high availability, redundancy, and resilient global routing. We continuously work toward 100% monthly uptime by monitoring every point of presence and rerouting traffic when network paths become degraded.
Because real-world internet routing depends on many external networks, local providers, and upstream paths, actual connectivity can vary by region and user network.
