Reporting & Delisting

How to report malicious IPs, how the scoring system processes your report, and how to request delisting.

01

Reporting an IP

Every report is recorded as a signal that contributes to the IP's total score. A single report will typically result in a score of ~6 points (Clean state), meaning the IP will NOT be blocked.

Via Web Interface

  1. Navigate to the DNSBL tool.
  2. Click "Report IP".
  3. Enter the IP, select category, provide reason.
  4. Submit - the report creates a signal and you'll see the resulting score and state.

Via API

POST https://provider.tools/api/dnsbl/report
Content-Type: application/json

{
  "ip": "1.2.3.4",
  "category": "spam",
  "reason": "Sending bulk unsolicited emails"
}

Response:
{
  "success": true,
  "reportId": "abc-123",
  "signalId": "sig-456",
  "score": 6,
  "listingState": "clean"
}

Why only 6 points? New/unverified reporters have a trust multiplier of ~0.75x applied to the base weight of 8. As your accuracy track record improves, the multiplier increases.

02

Delisting & False Positives

Automatic Delisting

Scores decay automatically over time. If no new signals arrive, your IP will return to Clean status within 14–60 days depending on the category.

Manual Delisting Request

  1. Fix the problem first - ensure your server is no longer compromised or sending spam.
  2. Check your IP on the DNSBL tool page.
  3. If listed, click "Request Delisting".

False Positive Process

If your IP was incorrectly listed, submitting a delisting request triggers a review. If confirmed as a false positive, the signals are marked accordingly and the reporter's trust score is reduced.
