What we do
IPScan turns a raw IP address into a clear, useful report: where it's registered, who operates the network, and whether the address looks like a datacenter, a VPN exit, or a mobile carrier. We pair the tools with plain-English articles that explain how the underlying technology works — IPv4 and IPv6, geolocation databases, ASNs, reverse DNS, all of it.
Who builds it
IPScan is run by a small, independent team with backgrounds in systems administration and web infrastructure. We've been operating high-traffic websites and dealing with the realities of IP-based traffic — bot detection, geo-routing, abuse handling — for over a decade. We built IPScan because the tools we wanted didn't exist in the form we wanted them.
Our principles
- No accounts. Looking up an IP shouldn't require a signup. We don't have an account system and we don't intend to add one.
- No paywalls on the basics. Geolocation, ISP, ASN, and reverse DNS will always be free here.
- Honest accuracy claims. Geolocation databases are wrong all the time. We tell you when a signal is heuristic instead of dressing it up as a definitive answer.
- Light pages. No autoplaying video, no five megabytes of frameworks, no popups that fight you for the close button.
Where the data comes from
Geolocation, ISP, and ASN data come from publicly available registry information (ARIN, RIPE, APNIC, LACNIC, AFRINIC), BGP route announcements, and commercial IP-to-location databases. Reverse DNS information comes directly from the operator's PTR records. We combine these sources to produce a single clean report.
How we make money
The site is supported by Google AdSense advertising. We don't sell user data, we don't run intrusive trackers, and we keep the ad load reasonable. If you find a tool useful, just using it (and not blocking ads, if that's an option for you) is the most direct way to keep it free for everyone else.
