As some said, don’t trust pricing or marketing claims, run your own benchmark based on your requirements.

Measurement-based probing has been used by major IP intelligence providers for years. Some just market it better than others But it’s not a silver bullet, a lot of IPs (mobile, CGNAT, enterprise) aren’t consistently probeable or yield ambiguous results.

In practice, no single method wins. Hybrid approaches usually perform better.

(For transparency: I work for https://ipregistry.co, worth including in your benchmark if you’re comparing providers.)
