What it requests
User agents claimed
Fingerprint family: 2 shapes, 84 IPs, 776 events in 30 days
Every shape here is within one request header of the family's largest shape and comes from the same source addresses. One tool, several request shapes; a hashed fingerprint shows these as unrelated.
HTTP/1.1, 5 headers, no body: accept, connection, accept-encoding, host, user-agent
Related fingerprints
Clients whose header set is within two of this one, measured from the tokens themselves.
About this fingerprint
Akin fingerprints an HTTP client from the request head alone: the protocol version, line endings, body framing, which headers are present, and the grammar of the negotiation header values. The User-Agent string and the request path are deliberately excluded, because both are trivially changed and both were measured varying within a single operator, so a scanner that rotates either keeps one fingerprint. The middle section is a presence bitmap rather than a hash, so two tokens can be compared directly to see how many headers the clients differ by.
