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
