DNS is the acronym for Domain Name Server, better known as the Domain Name System in the language of Cervantes. We explain what DNS is for and what are the 10 best servers you can use this year 2019.
What are DNS for?
DNS is a protocol that has the purpose of associating each domain name with an IP address . IP addresses are very difficult to remember, imagine having to memorize this sequence of numbers for each of the websites you visit each day. This is one of the reasons domains came about.
DNS servers work with a decentralized and hierarchical database that stores all the information about the domain names that exist on the Internet. Each of these domains is assigned the IP address of the server where the domain content is hosted.
Users' computers do not connect to the DNS server directly, but instead store the data of the domains and the IP associated with them in a cache . When entering a domain in the browser, it is checked if the IP address is stored in the cache, otherwise the computer will connect to the DNS server to obtain the necessary information. After that, this new information will be added to the cache to be able to obtain it more quickly the next time.
