IP Geolocation
Look up the location, ISP, and ASN of any IP address.
What Is IP Geolocation?
IP geolocation maps an IP address to a real-world location. It identifies the country, region, city, ISP, and timezone of any public IP address using a combination of WHOIS data and geolocation databases.
Use Cases
Common Use Cases
- Fraud detection — flag logins or transactions originating from unexpected countries relative to a user's normal location.
- Content localization — determine a visitor's likely country to serve region-appropriate content or pricing.
- Network troubleshooting — confirm whether traffic is routing through an unexpected region, which can indicate a misconfigured CDN or VPN.
- Verifying VPN/proxy usage — check if an IP resolves to a known hosting/datacenter range rather than a residential ISP, a common VPN indicator.
Example
Looking up an IP that resolves to a datacenter/hosting provider rather than a residential ISP is a strong signal the connection is coming through a VPN, proxy, or cloud server rather than a home or mobile connection.
Frequently Asked Questions
How accurate is IP geolocation?
Country-level accuracy is generally high. City-level accuracy varies and can be off by tens of kilometers, especially for mobile or ISP-shared IP ranges.
Can IP geolocation identify a specific person?
No. It identifies the approximate location of the ISP or network infrastructure serving that IP, not an individual or exact address.
Why does the location seem wrong?
This is common with mobile carriers, VPNs, and corporate networks, which often route traffic through infrastructure located far from the actual user.
What is ASN in these results?
The Autonomous System Number identifies the network/organization that owns the IP range, useful for identifying the ISP or hosting provider.
