DNS works by using a hierarchy of servers to look up and resolve domain names to IP addresses. When a user enters a domain name into their web browser, the browser sends a DNS request to a DNS server, which then checks its cache or forwards the request to other servers until the correct IP address is found and returned to the user’s browser.
Benefits of using DNS in web hosting:
- Improved website accessibility and user experience
- Greater scalability and flexibility in managing your website or server
- Better website performance through DNS-based load balancing
