IP checker

Paste any IPv4 address to see its geolocation, network, and whether it's a proxy, VPN, Tor exit, or datacenter address — with a fraud score. Free, no signup.

What it checks

Datacenter / hosting

matched against 3,649 cloud & hosting CIDR ranges — not a residential user

Proxy / VPN

anonymizing-network flags from live IP intelligence

Tor exit node

checked against the public Tor exit list, refreshed regularly

Geolocation

country, region, city, timezone and coordinates

ISP / ASN / org

the network operator behind the address

Reverse hostname

the PTR record, often a giveaway for hosting ranges

This is one endpoint of the Kaidn API. The full /v1/score adds device reuse, velocity, geo mismatch, email intelligence, custom rules, and plain-English explanations for every verdict. Start free or try the email checker.
