The Domain Name System (DNS) is one of the foundations of the internet. It is the phonebook of the internet. It converts human-readable domain names like www.hooptelecoms.com into Internet Protocol addresses like 220.127.116.11.
At its most basic, DNS is a directory of names that match with numbers. The numbers, in this case, are IP addresses, which computers use to communicate with each other.
