IP Lookup — Geolocation, ISP, ASN
Resolve any IP address to country, city, ISP, and ASN. Inspect your own IP, check log entries, or trace suspicious traffic — fast lookups, no API key needed.
How to look up the geolocation and ISP of an IP address
- Enter the IP. Paste an IPv4 (e.g. 8.8.8.8) or IPv6 (e.g. 2001:4860:4860::8888) address. Leave blank to look up your own.
- Read the location. See country, city, region, and approximate coordinates on a map.
- Check the network. View the ISP (e.g. Google), ASN (e.g. AS15169), and organization owner of the IP block.
- Check abuse signals. See whether the IP is on known threat lists (Tor exit, VPN, datacenter, abuse reports).
Frequently Asked Questions
- How accurate is IP geolocation?
- Country-level: ~99% accurate. City-level: 60–80% accurate. Mobile IPs can be off by hundreds of miles. Never use IP geo for security decisions.
- Does it work for IPv6?
- Yes. Both IPv4 and IPv6 are supported.
- What is an ASN?
- Autonomous System Number — the globally unique ID for a network operator. AS15169 = Google, AS32934 = Facebook, AS16509 = Amazon AWS.
- Can I look up multiple IPs?
- Yes. Paste a list (one per line) for batch lookup; results export to CSV.
- Is my query logged?
- Queries are routed via a public geolocation API. No personal info, just the IP being looked up.
- Why does my IP show a different city?
- ISPs often allocate IPs from regional pools, so your IP may map to the ISP backbone city rather than your physical location.
