The Domain Name System (DNS) is a hierarchical naming system for computers, services, or any resource connected to the Internet or a private network.
It associates various information with domain names assigned to each of the participants.
Most importantly, it translates domain names meaningful to humans into the numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide.
A frequently used analogy to explain the Domain Name System is that it acts as a “phone book” for the Internet by translating human-friendly computer hostnames into IP addresses.
