Datacenter IP Check

Name: GeoIPHub API
Availability: InStock
Author: GeoIPHub

Find out whether an IP address belongs to a hosting provider or cloud platform, and which one. Humans browse from residential and mobile networks; automation lives in datacenters.

How it works

890 ASNs, 10 cloud feeds.

Datacenter detection runs on two complementary datasets. The first is a curated set of 890 hosting ASNs, autonomous systems whose business is renting servers, from hyperscalers down to single-rack providers. The second is the official IP-range feeds published by 10 cloud platforms: AWS, Google Cloud, Azure, Oracle, Cloudflare, Fastly, GitHub, DigitalOcean, Linode, and Alibaba. When an IP falls inside a published cloud range, the verdict comes from the provider's own data, and the response can include the specific network.cloud_region.

WHOIS adds a third check: RDAP records across all five regional registries are scanned for 27 hosting keywords, which catches smaller providers that never make it into curated lists. Cloud ranges refresh weekly and the BGP/ASN table every three days, so verdicts track infrastructure changes.

Why it matters: almost no human browses the web from a cloud server. A signup, a checkout, or an ad click arriving from connection_type: datacenter deserves a closer look, which is exactly how the flag feeds GeoIPHub's fraud score.

FAQ

Frequently asked questions

What counts as a datacenter IP?

Any address operated by a hosting or cloud business rather than a consumer ISP: it either belongs to one of 890 curated hosting ASNs, falls inside an official cloud IP range, or carries hosting keywords in its WHOIS registration. The response also classifies the connection type (datacenter, residential, mobile) in asn.connection_type.

Does a datacenter flag mean the traffic is a bot?

Not by itself. VPN servers, corporate egress points, and legitimate monitoring services all run from datacenters. But genuine human browsing from a cloud IP is rare, so the flag is a strong signal. GeoIPHub weighs it inside the 0–100 fraud score rather than treating it as a verdict.

Which cloud providers are covered?

Official IP-range feeds from 10 platforms: AWS, Google Cloud, Azure, Oracle, Cloudflare, Fastly, GitHub, DigitalOcean, Linode, and Alibaba, plus 890 hosting ASNs covering providers that do not publish ranges.

How often is the data refreshed?

Cloud IP ranges and WHOIS data refresh weekly, and the BGP/ASN table refreshes every three days. Lookups themselves are served in under a millisecond from a memory-mapped database.
