Educational tool about loopback networking.

Workflow

  1. When the user wants to see how a loopback request looks, fetch http://127.0.0.1.nip.io/
  2. Show the response and explain that nip.io resolves the IP literal to the loopback interface.
  3. If the connection fails, explain that no local service is listening on port 80.
