Quick fix

Confirm that the listed IP is dedicated to or controlled by your organization.

What this finding means

SecuTest checks only resolved public IPv4 addresses and records source-specific return codes. Shared CDN or hosting IPs require careful attribution before remediation is assigned to the domain owner.

Interpretation boundary Use the exact evidence in your report. SecuTest reports externally observable conditions; it does not assume ownership, exploitability, or business intent when those cannot be proven remotely.

Why it matters

Security impact A public IP listed for spam, malware, or compromised-host activity can disrupt email delivery and indicate active abuse.

Step-by-step fix

Where to make the change

  • The compromised or abusive workload, sender, account, website, DNS record, or public IP identified in the evidence.
  • The named blocklist provider only after the root cause has been removed.

Remediation procedure

  1. Confirm that the listed IP is dedicated to or controlled by your organization.
  2. Investigate outbound mail, malware, proxy abuse, exposed credentials, and compromised workloads.
  3. Coordinate with the hosting or email provider for shared infrastructure.
  4. Request delisting after traffic and root cause are remediated.

Commands and configuration examples

Replace example values with the hostname, selector, IP address, port, or provider values shown in your SecuTest evidence.

dig +short A example.com
dig +short AAAA example.com

Verify the fix

  1. Verify the listing directly with the named provider.
  2. Inspect egress and mail logs for the affected IP.
  3. Confirm the IP is clear and abusive traffic has stopped.
  4. Repeat the SecuTest scan.
Confirm the externally visible result

After DNS, CDN, certificate, mail, or application propagation completes, run a fresh SecuTest scan and compare the new evidence with the original finding.

Re-scan your domain

Common mistakes

  • Assuming ownership of a shared CDN address.
  • Changing IPs without fixing compromised systems.
  • Treating a DNSBL provider error as evidence of abuse.
