Cloud Provider Detector — AWS, Azure, GCP & More

Public IP allocations attach organization names in WHOIS and geolocation databases — strings like Amazon Data Services, Microsoft Azure, or Google Cloud. Our matcher tests combined org and ISP text against regular expression signatures for each major provider in priority order.

First match wins with high confidence when a known hyperscaler pattern hits. If no named provider matches but hosting keywords appear, medium confidence generic hosting classification indicates cloud-like infrastructure without vendor specificity.

Signatures cover Amazon Web Services including EC2 and CloudFront patterns, Microsoft Azure, Google Cloud Platform, DigitalOcean, Hetzner, OVHcloud, Linode and Akamai Connected Cloud, Vultr, Oracle Cloud, IBM Cloud including SoftLayer legacy names, and Cloudflare.

Regional white-label hosts and niche providers may fall outside the signature list even when running on resold hyperscaler capacity. BGP route lookup and hosting provider tools add context when names stay generic.

High confidence means a specific provider signature matched — suitable for documentation and initial incident routing to the correct abuse portal family. Medium confidence generic hosting means keywords fired without a vendor-specific pattern — treat as cloud-like infrastructure pending further investigation.

None confidence with cloudDetected false means org strings looked like ISP, enterprise, or unknown allocations. That does not prove absence of cloud — only that our public metadata matchers did not recognize a major vendor.

Paste domains from SSL certificates, mail headers, or CDN logs. Resolution shows both query and resolved IPv4. Direct IPv4 entry skips DNS when investigating firewall allow lists or threat intelligence feeds already containing addresses.

Multiple cloud regions under one ASN may share org string prefixes — provider name identifies vendor, not specific region or availability zone.

Cloudflare matches as a CDN and edge provider — distinct from origin compute on AWS or GCP. Sites proxied through Cloudflare show Cloudflare org on edge IPs while origin may differ entirely. Use origin IP finder when you need backend cloud identification.

AWS CloudFront and Azure Front Door similarly appear under vendor signatures at the edge layer. Interpret provider name in context of whether you queried edge or origin addresses.

Security teams paste attacker IPs into cloud provider detector to choose the correct abuse workflow — AWS trust and safety versus Azure SOC versus GCP abuse forms. Provider name accelerates ticket filing even before full WHOIS parsing.

Combine with abuse contact finder for RDAP abuse mailboxes registered to the network block when provider portals require email-first reports.

Marketing analysts note which cloud powers competitor infrastructure from passive IP observations — combined with website technology detector for application stack context. Architects document hybrid cloud footprints by sampling public API endpoints.

M&A technical diligence records provider names alongside co-hosted domain density from hosting provider lookup.

Bring-your-own-IP blocks may show enterprise org names masking underlying hyperscaler. Dedicated instances without reverse DNS can display opaque allocation strings. Kubernetes node pools rotate addresses frequently — snapshot at investigation time.

Our embedded note reminds analysts that billing consoles and PTR records confirm what heuristics suggest.

Datacenter IP checker confirms the address is hosting-class network before you interpret cloud vendor names. IP to hosting provider adds reverse-IP co-tenant counts and sample domains on the same address.

BGP route lookup enumerates prefixes announced by the ASN when you pivot from single IP to full network footprint.

Extended API action cloud-provider-detector accepts query parameter with IPv4 or domain. Parse cloudProvider, cloudDetected, confidence, org, and asn fields into CMDB or SIEM enrichment pipelines.

Log confidence level when automating abuse routing — medium confidence generic hosting should not auto-map to a specific vendor portal.
