+      Stunner is a small Go CLI tool that sends STUN Binding Requests to
+      multiple Tailscale DERP servers (or any STUN servers you specify) and
+      reports the resulting NAT classification. This helps you determine
+      whether you're behind a Full Cone, Symmetric NAT, Restricted, or
+      otherwise, by analyzing how multiple STUN servers perceive your external
+      IP/port mapping.
