IPinfo's figures are from its VPN providers page as it stood on 2026-11-12, which gives each provider's IPs and no total, and its residential proxy data page, updated 2026-11-12. 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 IPinfo does more

IPinfo sells IP data at large: location to the city, the company and carrier behind an address, and its data as downloads. If you need those in the same call, IPinfo has more of it.

For VPN and proxy detection, ours answers more for less. The provider, a confidence and last seen come on every paid plan from $19 a month, where IPinfo names the provider only on Max at $163. Residential proxies carry 90 days of history against its 7, and the VPN flag is free with no cap, where its free plan has none.
