- Its DNS check uses 15 random hostnames; the page says their test services log which resolver requests them.
Field notes
The FAQ explains the DNS test as a set of 15 random hostname lookups: test services log which resolver asks for them, helping identify a resolver outside the VPN exit network. For travel routers, the browser times requests to common gateway addresses and compares them with two addresses used as baselines. The page also states a clear limit: it cannot inspect other apps’ traffic.
