The Domain Name System (DNS) is a system for naming online machines on the Internet. Just like visiting a friend, you must first know how other people’s homes go. When a host wants to access another host on the Internet, it must first know its address. The IP address in TCP/IP is a number separated by four “.” The composition is always not as convenient as the name, so the domain name system is used to manage the correspondence between the name and the IP.
