You're probably here because traffic from one of our scanner IPs turned up in your logs.
internetscan.org is a small, non-commercial security research project. We scan IPv4 networks across the Asia-Pacific region to see what services are publicly reachable, in a similar spirit to ZMap, Censys, and Shadowserver, just at much smaller scale. We don't attempt to log in, run exploits, or retrieve anything beyond the banners services hand back during a normal connection.
Scanner traffic comes from hosts with reverse DNS under
*.internetscan.org (currently just
scan.internetscan.org → 172.105.174.68;
more may be added as scope grows).
Send a note to abuse@internetscan.org with the IPs, CIDRs, or ASNs you'd like excluded and we'll add them within 24 hours.
The current exclusion list lives at /exclusions.txt.
