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 verified; one confirmed by neither is unverified. 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 confirmed traffic
The highest-volume fingerprints the operator's own traffic runs, per signal — claims confirmed via operator-published channels. A Match pill marks an exact match against a controlled capture — an association with known stacks, not an identity verdict: unrelated clients built on the same stack can legitimately share a fingerprint.
