Free • no sign-up • runs live in your browser.
What this tool shows
Enter an IP address or a domain (which is resolved to its IP first) to see its approximate geolocation, the ASN and ISP/organization that operates it, the timezone, and its reverse DNS (PTR) name. Useful for identifying where a server lives, who hosts it, and whether its reverse DNS is set correctly.
About IP geolocation accuracy
IP geolocation is approximate. It reflects the network operator's registration, not a precise street address, and VPNs/proxies/CDNs will show the provider's location rather than the end user's.
Frequently asked questions
Country-level accuracy is usually good; city-level is approximate and can be wrong, especially for mobile networks, VPNs and CDNs.
An Autonomous System Number identifies the network operator that announces an IP range — e.g. AS15169 is Google. It's the most reliable way to know who runs an IP.
Yes — this tool resolves the IP behind any domain, and you can paste your own public IP to see what the internet sees about your connection.
