What is DNS cache ? 🌐
The DNS cache stores the IP addresses of the web servers that host the web pages you have recently visited. Sometimes, this data may become outdated or incorrect, so you should delete it to improve your connection to the web servers.
If you need to clear the DNS cache, follow these steps.
🔹Windows
For each version of Windows, we recommend running the Command Prompt as an administrator due to the administrator rights settings.
In Windows 10, instead of the command line, the default command line is Windows PowerShell which is similar to the regular command line.
To clear it:
Click Start in the lower left corner and type Command Prompt or PowerShell in the search box
