Linux — resolvconf Introduction

<code>resolvconf</code> is a utility in Unix systems that manages multiple DNS configurations. It’s particularly useful in environments where the network configuration changes frequently. Below are few use cases where <code>resolvconf</code> might come in handy: <ul> <li>Mobile Devices and Laptops: Mobile devices and laptops often switch between different networks — for example, between home Wi-Fi, office Wi-Fi, and mobile data. Each of these networks might provide its own DNS configuration. resolvconf can help to dynamically update the DNS configuration as the device moves between these networks.</li> <li>Virtual Private Networks (VPNs): When a VPN is connected or disconnected, the network configuration, including DNS, can change. resolvconf can help to automatically manage these changes in the DNS configuration.</li> <li>Virtual Machines and Containers: In environments with lots of virtual machines or containers, the network configuration can change dynamically, particularly in cloud environments or when using tools like Kubernetes or Docker. resolvconf can help to manage the DNS configuration in these dynamic environments.</li> </ul> <a href="https://tonylixu.medium.com/linux-resolvconf-introduction-ab4fa9601a7a">Visit Now</a>
