The wire fingerprints traffic claiming to be this crawler presented, split by whether a channel the operator publishes for verification — its IP ranges or forward-confirmed reverse DNS — confirmed the claim.

Claims in window

Same adjudication as the stats page: a claim confirmed by either channel the operator publishes — its IP ranges or forward-confirmed reverse DNS — is legit; one confirmed by neither is spoofed. Operators differ in which channels they offer, and either alone fully identifies. Sources count distinct clients, not traffic. Fingerprint windows below are day-granular, like sources.

Fingerprints presented by unconfirmed claims

The impostor inventory: the highest-volume fingerprints wearing this operator's User-Agent that no operator-published channel confirms, per signal. A Match pill here shows known clients measured producing the same fingerprint an impostor presents.
