Terms of Use & Acceptable Scanning Policy
Terms of service, acceptable network scanning rules, liability limitations, and anti-abuse policies governing onmyport.com network diagnostic tools.
By accessing or using onmyport.com, you explicitly certify that you are the verified owner, authorized administrator, or possess explicit permission to probe the remote target IP address or hostname submitted to our scanner.
1. Permitted Use & Ownership Verification
onmyport.com is an open network diagnostic utility intended exclusively for:
- Verifying your personal home or office router port forwarding rules (e.g. Minecraft servers, Plex media, web services, SSH access).
- Diagnosing residential ISP port blocks (e.g. residential filtering of ports 25, 80, 445, or 139).
- Verifying whether local firewalls (e.g. Windows Defender, ufw, iptables) are correctly permitting inbound traffic.
- Diagnosing Carrier-Grade NAT (CGNAT) and double-NAT network topologies.
You are strictly prohibited from probing targets that you do not own or do not possess express written permission to test.
2. Prohibited Misuse & Unauthorized Reconnaissance
You agree not to engage in any of the following prohibited behaviors:
- Automated Mass Scanning: Scripting automated scrapers, headless bots, or batch scanning loops against arbitrary external CIDR ranges.
- Port Flooding & DoS: Using our edge servers as an amplification proxy to flood external network targets with high-volume TCP SYN packets.
- Rate Limit Evasion: Rotating residential proxies, spoofing IP headers, or attempting to circumvent our in-memory sliding-window rate limiters.
- Server-Side Request Forgery (SSRF): Attempting to submit loopback (
127.0.0.1), private RFC 1918 ranges (10.0.0.0/8,172.16.0.0/12,192.168.0.0/16), or cloud metadata endpoints (169.254.169.254). Our anti-SSRF guards drop these automatically.
3. Self-IP Restriction on Batch Probes
To prevent onmyport.com from being misused as an automated reconnaissance tool against third-party hosts, full suite multi-port scans (such as the “Top 20 Common Ports” scanner) are strictly restricted to the verified public IP address of the requesting visitor.
Attempts to launch parallel multi-port scans against external IP addresses or foreign domain names are automatically rejected with an HTTP 403 Forbidden status.
4. Diagnostic Accuracy & Limitation of Liability
All socket probe results are provided on an “as-is” and “as-available” basis without warranty of any kind, whether express or implied:
- Point-in-Time Diagnostics: A reported
OPEN,CLOSED, orFILTEREDstate reflects immediate edge socket handshakes. It does not certify that an underlying application or protocol is vulnerability-free. - No Liability for Security Incidents: onmyport.com, its maintainers, and infrastructure operators disclaim all liability for any system misconfigurations, unauthorized intrusions, data loss, router instability, or security incidents resulting from opening ports or configuring port forwarding on your network.
- User Responsibility: Securing local daemons with strong authentication, TLS encryption, IP whitelisting, and regular software patches remains entirely the user's responsibility.
5. Rate Limiting, Throttling & Abuse Enforcement
We enforce automated sliding-window rate limits to safeguard service reliability. We reserve the unrestricted right to immediately throttle, drop packets, or permanently block IP addresses or Autonomous System Numbers (ASNs) exhibiting abusive, abnormal, or malicious scanning patterns without notice.
6. Abuse Reporting & Inquiries
If you detect suspicious probe activity or suspect our platform is being abused, report the incident immediately to our security response team:
