What Is IP Geolocation?
IP geolocation is the mapping of an IP address to the geographic location of the device or server. It provides information such as country, city, ZIP code, latitude/longitude coordinates, ISP (Internet Service Provider), and ASN (Autonomous System Number). This data is useful for analytics, security, content localization, and network troubleshooting.
How to Use This IP Geolocation Lookup Tool
- Enter an IP address — Type or paste an IPv4 or IPv6 address into the input field. You can also click one of the example buttons (Google DNS, Cloudflare, GitHub, Fastly) to quickly load a sample address.
- Click Lookup — Press the Lookup button to fetch geolocation data. A loading indicator appears while the request is being processed.
- Review the results — The tool displays the IP address, country, region, city, ZIP code, latitude/longitude coordinates, timezone, ISP, organization, and ASN. Additional details include proxy/VPN detection and mobile network identification.
- View the map — The approximate location is plotted on an interactive map powered by OpenStreetMap. You can zoom and pan to explore the area.
Frequently Asked Questions
How accurate is IP geolocation?
IP geolocation accuracy varies by provider and location. Country-level data is very reliable, city-level is moderately accurate (often 60-80%), and exact street addresses are rarely possible. Mobile IPs may show the location of the network hub rather than the device itself.
Can I look up the location of any IP address?
This tool can look up any public IP address. Private IPs (like 192.168.x.x, 10.x.x.x) and localhost (127.0.0.1) cannot be geolocated since they are reserved for local networks and don't have a physical location.
Does IP geolocation reveal my exact home address?
No. IP geolocation typically identifies the general area (city or region) of an ISP's infrastructure, not the exact physical address of the device. It cannot pinpoint a specific building or residence.
What data source does this tool use?
This tool uses the ip-api.com service, which provides comprehensive geolocation data including country, region, city, ZIP code, coordinates, timezone, ISP, organization, ASN, and proxy/VPN detection.
Can I use VPN or proxy data from this lookup?
Yes. The results include proxy, VPN, and hosting detection flags. If an IP is associated with a VPN provider, proxy service, or data center, the tool indicates this in the Proxy/VPN field.
