Free IP Address Lookup for Developers
Our IP Address Lookup tool lets you resolve any public IPv4 or IPv6 address to geolocation and network details. Get country, region, city, timezone, ISP, ASN, and coordinates in one place—useful for debugging, analytics, or compliance checks.
What is IP geolocation?
IP geolocation maps an IP address to a physical location and network metadata. Databases combine routing data, registries, and voluntary submissions to estimate where an IP is used. Results are best-effort and can vary for VPNs, mobile networks, and data centers.
When to use an IP lookup tool
- Debugging: Confirm which region or ISP a request is coming from.
- Analytics: Understand where your users or API clients are located.
- Security: Spot suspicious or unexpected origins.
- Compliance: Apply region-specific rules (e.g. GDPR, geo-blocking).
Privacy and limits
Lookups are rate-limited per visitor to keep the service fair. We do not store the IPs you query. For high-volume or production use, consider a dedicated geolocation API or database.
