The Domain Name System, or DNS, is one of the Internet’s pillars that we utilize every day but don’t realize it. This system is like a telephone directory with the names of people. But instead of a phone, it uses an IP address corresponding to a domain name.
A brief history of DNS
The Domain Name System was created in 1980 by Paul Mockapetris. Until then, to access a website, you had to enter its IP. Since this process is prolonged and we can’t remember every single IP address, Paul invented the DNS system. To this day, it is the backbone of the internet.
