DNS flushing involves clearing the cache of your Domain Name System (DNS) resolver. DNS is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names, including IP addresses.
Your computer or device maintains a cache of recently looked-up DNS records to speed up future lookups. However, sometimes this cache can become corrupted or outdated, leading to various internet issues such as slow browsing, website inaccessibility, or connection errors.
Flushing the DNS clears this cache, forcing your computer to obtain fresh DNS records from the authoritative DNS servers for the domains you request. This process can resolve many common internet connectivity problems by ensuring that your device is using the most up-to-date DNS information.
Here's how to flush the DNS on different operating systems:
Windows:
1. Open the Command Prompt (cmd.exe) as an Administrator.
2. Type the following command: `ipconfig /flushdns`
3. Press Enter. You should see a confirmation message: "Successfully flushed the DNS resolver cache."
macOS:
1. Open the Terminal application.
2. Type the following command: `sudo killall -HUP mDNSResponder`
3. Enter your Administrator password when prompted.
4. You should see a message: "Stopping mDNSResponder...done."
Linux:
1. Open the Terminal application.
2. Type the following command: `sudo service nscd restart`
3. Enter your Administrator password when prompted.
Note: The specific commands and syntax may vary slightly depending on your Linux distribution.

In Microsoft Windows, you can flush the local DNS cache using the ipconfig /flushdns command in a Command Prompt. You know it works when you see the Windows IP configuration successfully flushed the DNS Resolver Cache or Successfully flushed the DNS Resolver Cache message.
