Your ultimate guide to the /etc/hosts file in Linux

The Linux operating system is known for its configurability and the power it gives to users to manage their systems. An integral part of this control comes from the ability to manipulate system files that govern how the operating system functions. One such critical file is the /etc/hosts file. This file is used by the operating system to map hostnames to IP addresses, acting as the first step in networking operations. Its understanding and management can play a crucial role in network troubleshooting and customization.
