Frequently asked questions
How accurate is IP geolocation?
Country-level accuracy is typically 95–99%. City-level accuracy drops to around 50–80% — IP geolocation is an estimate based on registry data and network routing, not GPS. VPNs and proxies will show the location of the exit node, not the real user.
What is an ASN?
An Autonomous System Number (ASN) identifies a network under a single administrative control, such as an ISP or large organisation. It's used for internet routing. For example, Google's ASN is AS15169.
Can I look up my own IP?
Yes — leave the field blank or enter 'me' to look up the IP address of the current request (our server's IP). To find your own public IP, visit a site like whatismyip.com.
