Domain name system (DNS) is one of the backbone networks of the Internet. You can't imagine running a website on a public network of millions of users around the world. If there is no DNS available and you need to visit the site using IP addresses, it is difficult to remember the IP addresses of the thousands of websites we visit every day. DNS is responsible for providing the IP address for the domain name, allowing us to access the website from the back-end Web server.

Why do I need to flush the DNS cache?

Sometimes, for some reason, the site will move to another server or simply change the IP address there. Now, it is DNS's responsibility to resolve the new IP address to allow unexplained site access. Our system keeps a cache of DNS records so that IP addresses can be parsed more quickly. It takes time to update the local cache after changing the IP address of any domain. At the same time, a page break error may occur. In this case, the local DNS cache needs to be flushed.
