The Engineering Reality of Network Telemetry
The tools, calculators, converters, and documentation provided on MyIPChecker are engineered to deliver rapid, reliable insights into internet protocol architecture. However, because computer networks depend on distributed routing policies, autonomous system agreements, and dynamic network address translation, diagnostic results must always be understood within their proper technical context.
This Accuracy Disclaimer outlines the physical and architectural limitations of IP geolocation, socket port verification, and proxy risk analysis to ensure our users interpret results responsibly and accurately.
1. The Realities of IP Geolocation: Why IPs Are Not GPS
The most common misconception regarding internet diagnostics is that an IP address can pinpoint a user's exact physical street address, building, or room. This is technically impossible.
An Internet Protocol address is a logical routing number assigned by Regional Internet Registries (RIRs) to Internet Service Providers (ISPs), educational institutions, and cloud data centers. It does not contain hardware GPS coordinates, nor does it interface with satellite navigation systems.
Statistical Granularity of Geolocation Databases
Modern commercial and open-source GeoIP databases (such as MaxMind GeoIP, IPinfo, ipwho.is, and DB-IP) compile location estimations through aggregated BGP announcements, WHOIS registrar filings, latency triangulation, and ISP gateway mapping. Independent academic research demonstrates the following accuracy tiers:
| Geographic Scope | Average Accuracy | Technical Certainty & Limitations |
|---|---|---|
| Country Level | 95% – 99% | Extremely high certainty. Misattributions typically only occur during sudden international IP block reallocations or cross-border satellite links. |
| Region / State Level | 75% – 85% | High to moderate certainty. Depends heavily on whether the ISP maintains geographically distinct regional subnets. |
| City / Metro Level | 50% – 75% | Moderate to low certainty. Often identifies the location of the ISP's regional routing hub rather than the subscriber's physical city. |
| Postal / ZIP Code | 20% – 40% | Low certainty. Usually represents the central postal code of an entire metropolitan switching office. |
| Street Address | 0.0% | Completely Impossible. IP addresses cannot identify street addresses, apartment units, or physical structures under any circumstance. |
2. Key Factors Affecting Geolocation Discrepancies
If our What Is My IP or IP Address Lookup tool displays a city or town different from where you are currently sitting, one of the following architectural factors is almost certainly the cause:
- ISP Points of Presence (PoPs): Residential internet traffic is funneled through your ISP's central switching facilities. If you reside in a rural town 40 miles outside a major city, your ISP may route all subscriber traffic through their primary metropolitan gateway. Geolocation providers see and record the gateway's coordinates, not your home.
- Carrier-Grade NAT (CGNAT) on Mobile 4G/5G: Cellular carriers connect millions of mobile smartphones using private address spaces behind shared CGNAT clusters. A single public IP address may be shared by thousands of mobile devices across an entire state or province, frequently resulting in location estimates hundreds of miles away.
- Satellite Internet Providers (e.g., Starlink): Satellite constellations utilize ground uplink base stations (teleports) located far from subscriber dish terminals. Your public IP address is anchored to the geographic location of the ground teleport station where your traffic enters the terrestrial fiber backbone.
- Dynamic IP Block Reassignment: ISPs frequently shift IP prefixes between service zones to balance traffic demand. If an IP block was reassigned from Chicago to Milwaukee last week, third-party GeoIP tables may take 30 to 60 days to reflect the update.
- VPNs, Proxies, and Tor Tunnels: If you utilize a privacy tunnel, your traffic exits onto the public internet from the host server. The coordinates displayed will reflect the location of the server's data center, which is precisely how privacy masking operates.
3. Port Checker Constraints and Shared Hosting Egress
Our Open Port Checker inspects socket connectivity on common application ports (e.g., HTTP 80, HTTPS 443, SSH 22, MySQL 3306) using a lightweight 3-second TCP socket handshake via fsockopen().
When reviewing port test results, please consider these technical realities:
- Egress Firewall Restrictions: In shared hosting environments (such as Hostinger), hosting providers routinely block outbound TCP connections on specific sensitive ports (such as SMTP port 25 or database port 3306) to prevent spam abuse and lateral botnet exploitation. When our server encounters such an outbound block, we display an honest notice explaining the hosting firewall rather than generating a false negative.
- Router NAT and Firewall Rules: A port on your home or office server may be open locally, but if your perimeter broadband router does not have active Port Forwarding configured, the port will remain unreachable from external public networks.
- ISP Inbound Port Filtering: Many consumer residential ISPs actively drop inbound packets targeting standard service ports (e.g., port 80, 443, or 25) to prevent residential customers from operating unmetered public web servers or mail relays.
4. VPN and Proxy Risk Indicators Are Not Legal Proof
Our VPN and Proxy Risk Checker evaluates multi-factor heuristics (including datacenter Autonomous System Numbers, proxy/hosting registry flags, and browser-versus-IP timezone discrepancies) to present an estimated privacy risk score.
These heuristics represent probabilistic indicators, not definitive guarantees. Certain legitimate enterprise networks, content delivery networks (CDNs), university campuses, or residential proxies may trigger elevated risk scores despite containing legitimate human traffic. Conversely, sophisticated private residential proxies may occasionally present low risk scores.
5. No Professional, Legal, or Forensic Advice
The diagnostic outputs and technical articles on MyIPChecker are provided for general educational and technical troubleshooting purposes only. They do not constitute:
- Legal evidence for civil or criminal court proceedings;
- Digital forensic certification for law enforcement investigations;
- Cybersecurity audit certification or regulatory compliance guarantees;
- Professional network engineering architectural advice.
You must not make high-stakes legal, financial, or infrastructural decisions solely based on the data outputs generated by this website. Always corroborate network findings with authoritative local command-line utilities (such as traceroute, dig, nmap, and Wireshark packet captures) administered by certified network professionals.
