02 — In the response

What a match looks like.

A lookup of a Pentest-Tools.com 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 Pentest-Tools.com but doesn't match is unverified.

GET /api/lookup/{ip}?key=PRO_KEY
{
  // … location and network fields …
  "risk": {
    "is_ai": false,
    "is_crawler": false,
    "is_scanner": true
  }
}

03 — Questions

About Pentest-Tools.com.

Does Pentest-Tools.com publish its scanner IP addresses?

Yes. Pentest-Tools.com publishes a list at https://pentest-tools.com/whitelist-ipv4.txt, which IPAPI.GR imports directly.

How do I verify Pentest-Tools.com with reverse DNS?

Look up the PTR record for the IP address. The hostname must be one of scanners.pentest-tools.com, and a forward lookup of that hostname must return the same IP address. A PTR record alone can be set by anyone who controls the address, so the forward confirmation is the part that matters.

How often is the Pentest-Tools.com list refreshed?

IPAPI.GR re-fetches it every 15 minutes. If a refresh fails, the previous entries expire after at most 24 hours instead of being trusted forever.

Which risk flag does Pentest-Tools.com set?

A matching address sets risk.is_scanner in the lookup response. The risk flags are returned for Pro API keys.
