Domain Name System (DNS) is a system to solve the problem of online machine naming on the Internet. Just like visiting a friend and saying goodbye to the prophet how to get there, when a host wants to access another host on the Internet, it must first know its address.
The IP address in TCP/IP consists of four numbers separated by "."(here, take the address of ipv4 as an example, and the address of IPv6 is the same), which is not as convenient as the name to remember, so the domain name system is adopted to manage the corresponding relationship between the name and IP.
Although all nodes on the Internet can be uniquely identified by IP addresses and can be accessed through IP addresses, even if the 32-bit binary IP address is written in four decimal forms from 0 to 255, it is still too long to remember. Therefore, people invented the domain name, which can associate an IP address with a set of meaningful characters.
When users visit a website, they can enter the IP address and domain name of the website, which is equivalent to access.
For example, the IP address of Microsoft's Web server is 207.46.230.229, and its corresponding domain name is www.microsoft.com, so users can visit its website no matter whether they enter 207.46.230.229 or www.microsoft.com in the browser.
