IP Geolocation Lookup

Shows the country, region, city, ISP, ASN and approximate coordinates for any IP address — leave the field blank and it looks up your own. Comes up in security investigations, general network troubleshooting, and confirming a VPN is actually exiting where you think it is.

How accurate this actually is

IP geolocation works off databases maintained by regional internet registries, and the accuracy drops off fast as you get more specific. Country-level is generally solid — 95%+. City-level is much softer, often only 50–80% reliable, because ISPs frequently register address blocks to a head office or data centre rather than to wherever the connection is physically being used. Treat it as a strong hint about general location, never as proof of exactly where someone is.

ASN — the more genuinely useful field here

An Autonomous System Number identifies which organisation actually operates a given network — an ISP, a cloud provider, a large enterprise running its own address space. Knowing the ASN behind an IP is often more useful than the geolocation itself: it tells you whether you're looking at a residential connection, a known cloud provider's range, a CDN edge node, or a VPN exit — which matters a lot more for triage than "which city is this roughly in."

Where this earns its keep

• Sanity-checking the origin of a suspicious login attempt before deciding how seriously to treat it
• Confirming a VPN is actually routing through the country it claims to be
• Debugging CDN routing or geo-restriction issues that only reproduce from certain locations
• Figuring out at a glance whether an IP belongs to a known cloud provider or ISP versus something that looks a lot more like a compromised residential machine
