@@ -304,6 +304,24 @@ When a `QuicError` is passed to [`stream.destroy()`][] or
 `STOP_SENDING` frame sent to the peer. Any other error type falls back to
 the negotiated protocol's generic internal error code.
 
+### Permission model
+
+When using the [Permission Model][], the `--allow-net` flag must be passed to
+allow QUIC network operations. Without it, calling [`quic.connect()`][] or
+[`quic.listen()`][] will throw an `ERR_ACCESS_DENIED` error.
+
+```console
+$ node --permission --allow-fs-read=* --experimental-quic index.mjs
+Error: Access to this API has been restricted. Use --allow-net to manage permissions.
+  code: 'ERR_ACCESS_DENIED',
+  permission: 'Net',
+}
+```
+
+Creating a [`QuicEndpoint`][] instance without connecting or listening
+is permitted even without `--allow-net`, since no network I/O occurs until
+[`quic.connect()`][] or [`quic.listen()`][] is called.
+
 ## `quic.connect(address[, options])`
