Understanding Loopback Interface
The Loopback Interface is a virtual network interface in a system that allows it to communicate with itself. It is commonly assigned the IP address 127.0.0.1, enabling local services and applications to interact with network services running on the same machine. This interface is crucial for testing and troubleshooting network configurations without relying on external connections.
