What is Domain Name System (DNS)?

DNS is an Internet service that resolves domain name (human-readable), such as www.example.com, into IP addresses (machine-readable).

Domain names are alphabetic, they’re easier to remember, but the Internet is really based on IP addresses, and this reason makes DNS one of the foundations of the internet, and most people probably don’t realize they use it every day.

The DNS system is, in fact, its own network. If one DNS server doesn’t know how to get a particular IP of domain name, it asks another one, and so on, until the correct IP address is returned.
