What is Ubuntu Server DNS?

Ubuntu Server DNS is a domain name system that translates domain names into IP addresses. It’s an open-source platform developed by Canonical. Ubuntu Server DNS is a scalable and versatile solution for website owners and system administrators who want to manage their DNS in-house. It’s designed to provide excellent performance, reliability, and security, making it a popular choice among developers globally.

How Does Ubuntu Server DNS Work?

Ubuntu Server DNS works by serving as a directory of domain names and their corresponding IP addresses. When a user types a domain name into the browser, the request is sent to the Ubuntu Server DNS, which then translates the domain name into an IP address. The IP address is then used to connect to the website’s server. Ubuntu Server DNS makes use of a hierarchical domain name structure, which allows it to function efficiently and at scale.
