In this article, we’ll explain how to change your DNS settings on a Mac. DNS stands for Domain Name System. Think of DNS as a phone book for the internet that translates domain names (like “bitdefender.com”) into numeric IP addresses (like “22.214.171.124”), allowing you to visit websites without having to remember their IP. By changing DNS, you can direct your internet connection to use a more reliable DNS server. This can help if you’re having trouble connecting to certain websites or applications, encountering Bitdefender update errors, VPN errors, or if your internet speed is slow.

This action reverts your settings back to your Internet Provider’s default DNS server.
