What is the role of domain name server?

Domain name server (DNS) is used for domain name resolution. It will convert it into an IP after you enter the URL online, and then access the other party's server. Without it, you can't go to Baidu if you want to. To remember Baidu's IP, you need to remember the IP of 163 when going to 163. With DNS processing, you only need to remember the domain name of the corresponding website-that is, the URL.

DNS stores a table of domain names and corresponding IP addresses to resolve the domain names of messages. A domain name is the name of a computer or computer group on the Internet. It is used to identify the electronic location (sometimes also the geographical location) of the computer during data transmission. A domain name is a string of dot-separated names, usually including the name of an organization, and always includes a two- or three-letter suffix to indicate the type of organization or the country in which the domain is located.
