Title: Internet and Web Browsers. DNS
Auto-description: This video explains the purpose and structure of the Domain Name System (DNS). It describes how the DNS facilitates Internet use by translating IP addresses, which are difficult-to-remember series of numbers, into easier-to-remember and use domain names, such as "www.google.com." Domain names operate hierarchically and are managed in a decentralized manner, respecting the principles of Internet organization.
It details how, within the scope of a top-level domain (TLD), such as ".com" or ".es," there are subdivisions ranging from second-level domains (e.g., "google.com") to more specific or lower levels (e.g., "www.dsic.upv.es"). These subdivisions or subdomains are managed by various entities, allowing for a systematic and hierarchical distribution of names on the Internet.
It mentions that the DNS system is composed of authority zones and records name changes, which are propagated throughout the network so that any device can recognize them. In addition, the evolution of TLDs is explained, starting with the original six specific to the United States (com, net, org, int, edu, gov, mil) to the inclusion of country codes and the recent approval of new generic TLDs such as ".academy" or ".bar."
Finally, the process by which a service or individual can register a domain name associated with an IP address is addressed, using domain name registrars available over the Internet, which allows for easier access to said service on the Internet.
