Simply put, it is the process of converting domain names that you can understand (for example: daicuo.cc) into their corresponding IP addresses. Without DNS, we cannot find the server. In the network, connections and transmissions are determined by the method of IP + port to identify the location of a resource! So, when we enter a domain name, the network does not actually recognize it. Here, we need the DNS server to help us exchange the domain name into an IP!

The resolution speed and regions of each are different, and the philosophies they promote are also somewhat different, but they all perform domain name resolution to IP. Some advertise stability and speed, while others boast no hijacking, security, and stability! Choose the one that suits your own route and what you consider to be clean! Sometimes, you may encounter a situation where a website suddenly cannot be accessed, but changing the DNS works. This is because your original DNS can no longer resolve the domain name you are visiting, causing the visit to fail. By changing to another provider that still has the domain name resolution, it works!
