IP & Proxy Checker
Check any IP address for location, ASN, and datacenter/hosting provider detection — the same network signal DataSec uses at scale.
This is one signal among many
DataSec combines ASN/datacenter signals like this with device fingerprinting, TLS fingerprinting, and behavioural analysis — not just IP checks alone. Motivated bot operators route through residential proxies specifically to defeat IP-only checks. See how multi-layer detection works →
Frequently asked questions
How accurate is this tool?
Country and city accuracy depends on MaxMind's GeoLite2 database — country-level accuracy is generally above 99%, city-level around 80%. ASN/organisation data is typically very accurate since ASN allocations are public record.
Does this tell me if an IP is a VPN specifically?
This tool flags known datacenter and hosting provider ASNs as a strong proxy-usage signal — but it's not a certainty. Detecting VPNs specifically requires MaxMind's paid GeoIP2 Anonymous IP database, which adds direct isVpn, isAnonymousProxy, and isHostingProvider fields. We're transparent about this limitation.
Do you store the IPs I look up?
Yes — we log IP lookups (including the IP address queried and basic geo/ASN data) to analyse tool usage and qualify leads for the DataSec platform. We don't sell this data. See our Privacy Policy for full details.
