Use Cases
- Testing out a website on a local machine using a local server like XAMPP. Just do localhost:(insert TCP/UDP port number). Sometimes you don't have to remember the port number and can just use the name of the software. Examples: localhost:wordpress , localhost:xampp, localhost:phpmyadmin, etc.
- Web UI for self-hosted software on your local network. For instance, if enabled in the settings, you can use a web interface for QBitTorrent on port 8080.
