Is this IP really Silent Push?

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

01 — Verification

How IPAPI.GR verifies Silent Push.

Only from what Silent Push 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 Silent Push 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 Silent Push 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 Silent Push.

Does Silent Push publish its scanner IP addresses?

Yes. Silent Push publishes a list at https://scanning.silentpush.com/, which IPAPI.GR imports directly.

How do I verify Silent Push with reverse DNS?

Look up the PTR record for the IP address. The hostname must end in .scanning.silentpush.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 Silent Push list refreshed?

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

Which risk flag does Silent Push set?

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