academic internet measurement scanner of the Max Planck Institute for Informatics (DE). Not an SEO tool. The scan IPs are self-identifying: reverse DNS inet-research-scan-*.mpi-inf.mpg.de. Found in the CINS cross-check and completed via neighbor-range scan — each IP reverse-confirmed (26). Part of our PARC Security feed.

Verification — every IP individually
The reverse PTR inet-research-scan-*.mpi-inf.mpg.de can only be set by the IP operator — a non-forgeable ownership hint. Seeded from the actively scanning CINS IPs, completed via reverse scan of the surrounding /24s; each IP confirmed individually:
26 IPs → all PTR mpi-inf.mpg.de
Reverse-only (forward not consistently checkable, like Shodan/Infrawatch). AbuseIPDB partly lists these at score 100 — they are benign research scanners nonetheless.
