 - The `getLocalhostPublicIp` method is useful for checking if the client is from localhost. Uses https://api.ipify.org/?format=json endpoint.
 - In laravel native way you can use `Request::ip()` method but this method is cover all cases. For example cloudflare, nginx, etc. Also see this stackoverflow [question](https://stackoverflow.com/q/13646690/6940144).
