DNS Server Isn’t Responding: Causes, Symptoms, and How to Fix It

DNS Server Isn't Responding

Understanding DNS Servers

A DNS server, or Domain Name System server, is a critical component of the internet infrastructure that translates human-readable domain names (like google.com) into IP addresses that computers can understand. When you enter a website’s URL into your browser, your computer sends a request to a DNS server to obtain the corresponding IP address. The DNS server then sends back the IP address to your computer, allowing it to connect to the website.
