“IP purity” is IPOK's summary label for visible IP-side evidence such as proxy, VPN, hosting, blocklist, and abuse signals. It is not a third-party platform's internal score.
IPOK shows source values and flags side by side and publishes its own weights and floors. The result only describes evidence IPOK currently sees; it cannot predict a sign-up, commerce, social, or AI-service decision.
These are IPOK's own bands: below 15 Pristine, 15 to below 50 Clean, 50 to below 70 Risky, and 70 or above High Risk. They are not a pass threshold for another platform.
No. Datacenter is a network-use classification. IPOK applies a contextual floor of 35, while proxy, abuse, and blocklist evidence depends on the returned sources; this does not predict a platform outcome.
Each source uses different blocklists and update cadences. Comparing multiple sources gives a fuller picture — exactly what IPOK does.
