Switching DNS on Windows 11 helps your computer speed up its internet connection, especially during fiber optic network interruptions. In this article, Software Tricks shares how to change DNS on Windows 11 to improve network speed.

1. What is DNS?
DNS, short for Domain Name System, is a system that translates domain names into IP addresses. The functioning of DNS is similar to a map or directory for websites on the Internet. DNS helps users remember names instead of complex strings of numbers when trying to access a website.

In Vietnam, Internet Service Providers (ISPs) have pre-configured DNS for users (known as default DNS). However, these default DNS from ISPs are often slow and unreliable as ISPs can track users' activities. Hence, your internet connection is no longer private.
