Is this IP really Modat?

Checks the address against what Modat publishes, the same evidence behind risk.is_scanner.

01 — Verification

How IPAPI.GR verifies Modat.

Only from what Modat publishes about itself. No third-party blocklists, no behavioural guesses. Live address counts change with every publication, so check the official file for the current list.

02 — In the response

What a match looks like.

A lookup of a Modat 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 Modat 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 Modat.

Does Modat publish its scanner IP addresses?

Yes. Modat publishes a list at https://scanner.modat.io/ipv4.txt, which IPAPI.GR imports directly.

How do I verify Modat with reverse DNS?

Look up the PTR record for the IP address. The hostname must end in .scanner.modat.io, 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 Modat 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 Modat set?

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