Common Errors & Troubleshooting

404 Not Found The IP address is in an unrecognized format or the endpoint path is wrong.
✓ Pass a valid public IPv4 address directly in the URL path, e.g. https://ipvigilante.com/203.0.113.1.
Service unavailable The free API may experience downtime as it has no SLA guarantees.
✓ Add error handling and retry logic. Consider a backup service like ipinfo.io for production use.
Inaccurate location data IP geolocation databases are approximate and can be outdated.
✓ Use IP geolocation as a hint only, not a precise location source. Inform users accordingly.
