Look up geolocation and ISP information for any IP address
Lookup
What this tool does
Looks up any IPv4 or IPv6 address and returns country, region, city, ISP, ASN, timezone, and whether the IP is a known proxy/VPN/TOR exit or hosting datacenter. Backed by proxycheck.io and cached in MySQL for speed.
Who it's for: Security engineers investigating access logs, ad fraud analysts checking traffic quality, and anyone curious about an IP's origin.
When to use
- •Check if a suspicious login came from a VPN or TOR exit node.
- •Classify traffic sources in access logs by country.
- •Verify that an ASN matches a known cloud provider.
- •Research incoming scrapers' hosting providers.
How it works
- 1Enter any IPv4 or IPv6 address.
- 2The server queries proxycheck.io and returns location + threat data.
- 3Results are cached 24h so repeat lookups are instant.
- 4Your own IP can be looked up with one click.
Tips
- •Proxy/VPN classification isn't 100% - rotating residential proxies often pass.
- •ASN tells you the network owner; cross-reference with BGP data for exact routing.
- •Timezone from IP doesn't always match the user's browser timezone - spoofing tells.
