ipgeolocation.io's figures are from its post on VPN detection false positives (2026-11-04) and its security database page, read on 2026-11-13. Ours are counted from 2026-11-13's build of the data every lookup answers from. No independent list of every VPN address exists to test the APIs against, so each count is the company's own.

Where ipgeolocation.io does more

ipgeolocation.io's security answer reaches past anonymity: a threat score, bots and who runs them, known attackers, spam, and corporate gateways such as Zscaler. Its bulk call takes 50,000 addresses at once.

For VPN and proxy detection alone, ours answers the same questions for less: 250,000 lookups for $19 where its $19 buys 75,000, every field on every plan, datacenter, mobile and public proxies each flagged on their own, and 90 days of proxy history against its 30.
