Bot signals — Internet scanner
Infrawatch is an internet scanning project in the IPAPI.GR scanner catalogue. Addresses it publishes or verifiably identifies as its own set risk.is_scanner.
Our catalogue has no official documentation page for Infrawatch, so this page only describes the verification rule below. Addresses are flagged only when that rule matches.
01 — Verification
Only from what Infrawatch publishes about itself. No third-party blocklists, no behavioural guesses.
risk.is_scanner
.infrawat.ch.
The hostname must then resolve forward to the same address.
02 — In the response
A lookup of a Infrawatch address sets risk.is_scanner. The flags come with geolocation and network data in the same response, for Pro API keys.
The response says which kind of bot an address belongs to, not which operator. Pair it with the user agent: a request that claims to be Infrawatch but doesn't match is unverified.
