Criminal IP alternative — you don't need a whole threat-intel platform to check one IP

Platforms like Criminal IP are for security teams: they need asset mapping, scan intel, and vulnerability profiles, so they come with account systems, credit billing, a query syntax, and a full UI. The learning and account cost you pay buys depth and breadth for ongoing security operations.

But "is this IP a proxy / datacenter, is it clean" is a lightweight, frequent, one-off need. Registering a threat-intel platform, buying credits, and learning its usage for that is using a heavy tool for a light job — most of the time you just want an instant, explainable verdict.

When checking an IP by hand, what's useful is a few things together and immediately available: an aggregated multi-source risk / purity verdict (not a single black-box score), native-vs-datacenter (which decides whether ChatGPT / streaming / banks accept it), a /24 neighbor profile (guilt-by-association risk), and a WebRTC/DNS leak test to self-check whether your own proxy is leaking your real IP.

IPOK puts these on one no-signup page: enter an IP and get an aggregated 8-source verdict + native/datacenter + /24 profile; the leak self-test runs only on click, stays local, and is never sent back. It doesn't do asset mapping or vulnerability intel like a platform — but for "I just want to vet this one IP," it's faster, simpler, and doesn't tie you into an account system.
