IP Lookup retrieves geolocation and network information for any IPv4 or IPv6 address: country, region, city, ISP, ASN (Autonomous System Number), latitude/longitude, and timezone. Useful for debugging CDN routing, identifying the origin of traffic, security investigations, and understanding where your users are connecting from.
How it Works
1Enter an IPv4 or IPv6 address in the input field, or click 'My IP' to look up your own.
2The tool queries a geolocation database API.
3Location data is displayed: country, region, city, ISP, ASN, and coordinates.
4Copy individual fields or the full JSON response.
Frequently Asked Questions
How accurate is IP geolocation?
Accuracy varies by level. Country-level is typically 95%+ accurate. City-level accuracy drops to 50–80%, as IP blocks are assigned to ISPs rather than individual buildings. For mobile users, the ISP's city (often a regional hub) is returned rather than the actual device location. Corporate VPNs and proxy servers return the exit node location, not the user's location.
Can I look up private IP addresses like 192.168.x.x?
Private IP addresses (RFC 1918 ranges: 10.x.x.x, 172.16–31.x.x, 192.168.x.x) are not routable on the public internet and have no geolocation data. The tool will indicate that the address is private/reserved.
What is an ASN?
An Autonomous System Number (ASN) identifies a network under a single administrative domain (an ISP, cloud provider, or large organisation). ASN data tells you which organisation owns and routes the IP block. For example, AS16509 is Amazon Web Services, AS15169 is Google. This is useful for identifying cloud providers, CDNs, and known hosting ranges.
Does the tool work for IPv6 addresses?
Yes. Enter a full or abbreviated IPv6 address (e.g. 2001:db8::1) and geolocation data will be returned for it, subject to the same accuracy limitations as IPv4.
