What is DNS?
DNS is the acronym in English for Domain Name System , which in Spanish means Domain Name System. As the name implies, it is a registry that contains website names and associated IP addresses.

That is, each element on a website is sent in a package and interpreted by the computer that sees that information. Images, texts and videos are divided into packages and sent gradually.
However, each machine on the network only communicates with another when it knows its IP. If computer X wants to receive packets from Y, it must first initiate an interaction with Y. This is only done if X knows Y’s IP number. The interaction starts with a kind of lookup for Y’s number.
