What it does
nthLink supplies free VPN-tunnel apps with an address-discovery method intended to keep connections available where known addresses are blocked.
nthLink's practical feature is fresh server discovery. The official FAQ says the mobile app derives current server addresses using device and location context, then keeps trying when addresses are blocked. That is the behavior to evaluate in a restrictive network, rather than assuming an old bundled list will still connect. The service is sponsor-funded and free. Its data description also acknowledges collecting operational details such as IP address, device type and operating system, so free access should not be confused with collecting no data.
