LNA Prompt

Type an arbitrary target URL and watch the LNA classifier decide whether it would prompt, allow, or block. Then actually fetch the URL — Chrome 141 ships the new prompt for any public-origin request to a private/loopback address.

this origin: —
target: —
no classification yet.

the classifier

// Local Network Access categories (per spec):
//   loopback  — 127.0.0.0/8, ::1, localhost
//   private   — 10/8, 172.16/12, 192.168/16, link-local, etc.
//   public    — everything else (including this page on the open web)
//
// Rule: public  → private   ⇒ permission prompt + preflight
//       public  → loopback  ⇒ permission prompt + preflight
//       private → loopback  ⇒ permission prompt + preflight
//       same-or-broader      ⇒ allowed without prompt
