Global Internet Come into a New DNS Era

Abstract DNS, short for Domain Name System, is an analytic central system, which transfers domain names into IP addresses that can be identified by the Internet. DNS has internal traits within it to conduct commands and regulations in network communication, as well as centralized ones that are inherently political. Unlike other Internet protocols, DNS protocols penetrate the Application Layer, the Internet Layer, the Transport Layer, and provide even more complicated, tailored low-level software that are feasible to the DNS, ranging from authorized Domain Name Servers to Recursive Domain Name Servers, a domain system based Content Distribution Network (DN-CDN), whether private or public, inside or outside the network, it must be dependent on the service provided by Domain Name System (DNS). DNS includes the increase in Client Subnet in DNS Extension Mechanism (EDNS) to conduct more accurate matches to push service.
