IP intelligence, address by address

Every address gets a live verdict from the same pipeline the API serves: VPN, proxy, Tor, and datacenter signals, a 0–100 risk score, and an allow, review, or block decision. Use the free lookup tool to check any address, or open an address page directly at /ip/<address>.

Pages for residential and mobile addresses render for you but are not indexed by search engines. Sentinel only publishes crawlable pages for infrastructure that operators document themselves — provider-published cloud ranges and the Tor Project's exit list — rather than reputational judgements about consumer broadband lines.

Datacenter space, by provider

One address from each provider's own published range list. The full footprints are in the hosting directory.

Current Tor exit nodes

A sample from the Tor Project's published exit list, which we refresh every four hours. Tor traffic is not fraud by default — but it is worth a second factor before an irreversible action.

What the verdict is for

A score is a starting point, not a decision. Reading a page from a flagged address is unremarkable; redeeming a promotion or completing a checkout from one deserves scrutiny in proportion to what the action costs.

To find out who announces an address rather than whether it is a tunnel, use the ASN directory — that is a different and equally useful question.
