InternetMeasurementBot

InternetMeasurementBot is part of driftnet's measurement of publicly exposed services. Unlike an uptime check created by a site owner, it can reach a service because an address and port are open on the internet. Driftnet attempts a protocol-level exchange and records what the public service returns.

For HTTP endpoints, the resulting scan data can include URLs, hostnames, response headers, and page titles. Driftnet also documents an API for retrieving full HTTP response bodies collected during a scan. A request may therefore reveal more than a port number when the endpoint answers without authentication.

The recorded user-agent token is InternetMeasurementBot, but this entry has no IP verification. Anyone can copy that header, so it should be treated as a classification clue rather than proof of origin. Driftnet explains its scanning and offers an opt-out route, but its public material does not state whether this token follows robots.txt.

This scanner is not documented as an AI crawler. Its observations support internet measurement and security work, with no stated use in AI search results or model training. The useful response to an unexpected hit is to review what the endpoint exposes publicly.
