What Does Flushing DNS Server Do?

Have you ever encountered a situation where you visited a website, and it failed to load? Or maybe you changed your website’s hosting provider, and the changes are not reflecting?

These issues can often be resolved by flushing the DNS server. In this article, we will explore what flushing the DNS server means and how it can benefit you.

Understanding DNS

DNS stands for Domain Name System. It is like a phone book for the internet.

When you type a website URL into your browser, the DNS translates that human-readable name into an IP address that computers can understand. It acts as a directory that maps domain names to their corresponding IP addresses.

DNS servers store this mapping information in their cache, which helps in speeding up future requests to the same domain. However, sometimes these cached entries become outdated or corrupted, causing problems accessing websites or services.

What is Flushing DNS Server?

Flushing the DNS server refers to clearing its cache of stored IP addresses and domain names. When you flush the DNS server, all the outdated or corrupted entries are removed from its cache. This forces your computer to query fresh IP addresses from authoritative DNS servers when accessing websites.

The Benefits of Flushing DNS Server

1. Resolving Website Loading Issues:
