What Is a Domain Name Server ?
A Domain Name Server (DNS) is an integral part of the internet’s infrastructure. It serves as a phonebook, converting domain names (such as google.com) into IP addresses that computers can comprehend. DNS servers are in charge of organizing and distributing domain information, guaranteeing that users can access websites and services. In simpler terms, a DNS server aids in connecting your browser to the correct website when you enter a URL. Understanding the function of a domain name server is crucial for troubleshooting DNS errors and resolving connectivity issues.
What Are Common Domain Name Server Errors?
When it comes to managing a website, encountering domain name server errors can be a frustrating and confusing experience. In this section, we will discuss the most common DNS errors that website owners may encounter. We will outline the various types of errors, including DNS server not found, DNS server unavailable, DNS server timed out, and DNS server failed. By understanding these errors, you can effectively troubleshoot and resolve any issues that may arise with your website’s domain name server.
