localhost link differs from the network link in React app example.

[Numel2020]

Describe the bug

hello I am not sure if this is a bug, but I need to confirm two things. I can access my app through the localhost link which is http://localhost:3000 and http:192.xx.1.xx.3000. however I get two different pages. on the localhost link i see a progressive web apps template page and on the other link i see the react app example page with the spinning react logo.

Is this the correct behaviour of create-react-app?

Many thanks.
