## What it means

A VPN shifts trust and the visible route; it does not make a device or browser anonymous by itself. DNS, IPv6 and split-tunnel behaviour need deliberate configuration.

## For hosting

A self-hosted endpoint can be useful for private access. Keep it updated and understand what the VPS and upstream can still observe.

## Which traffic actually enters the tunnel?

Test routes, DNS and both internet address families from the client. A split-tunnel setup can be correct when that is the intended design.
