Most of your alerts
are just business.
CDNs, update servers, public DNS, SaaS APIs and monitoring probes generate a constant stream of traffic that looks like activity and almost never is. SourceIP tells you which operator an address belongs to, so your analysts spend their time on the rest.

Every range has a source
Ranges come from the operator's own published lists such as a provider config, an SPF record, a documented API endpoint. Nothing is inferred from traffic observation.
Trust levels, documented
A match on a provider's own control plane means something different from a match on infrastructure they rent to customers. SourceIP grades that difference explicitly instead of flattening it into one score.
Reviewed by hand, provider by provider
Every provider in the dataset has been through an analyst's hands before it reaches yours. Every source checked against the operator's own domain, ownership confirmed, edge cases split out rather than lumped together. Our judgment is the product.
| Level | Meaning | Tag |
|---|---|---|
| 1 | The provider directly operates the service (e.g., API endpoints, DNS, software delivery, or control-plane infrastructure published by the operator itself). | TRUSTED |
| 2 | Ownership is known, but the provider supplies infrastructure to customers or third parties, so activity is not attributable to the provider itself. | SHARED INFRASTRUCTURE |
| 0 | Descriptive context only — the match provides information without serving as a basis for trust or distrust decisions. | INFORMATIONAL |
| -1 | Important to label, but a match must not imply benign behaviour, accountability, or allow-list suitability. | UNTRUSTED |
SourceIP is an attribution dataset. A trust level describes what a match means. Only our TRUSTED level should be used for whitelisting. The others are for context and should be treated as advisory.
