Introducción al DNS:
1. El DNS (Domain Name System, Sistema de Nombres de Dominio) es un sistema distribuido, jerárquico y adaptativo, que constituye una de las infraestructuras indispensables de Internet y se utiliza para resolver nombres de dominio y devolver la dirección IP asociada a ellos.
2. El DNS convierte los nombres de dominio (como www.example.com) en direcciones IP que los ordenadores pueden procesar (como 192.0.2.1).
3. Los tipos de consultas DNS incluyen los siguientes:
(1) Registro A: resuelve un nombre de dominio en una dirección IPv4.
(2) Registro AAAA: resuelve un nombre de dominio en una dirección IPv6.
(3) Registro CNAME: resuelve el nombre de dominio en otro nombre de dominio.
(4) Registro MX: designa el servidor de intercambio de correo, utilizado para el sistema de correo electrónico.
(5) Registro NS: designa el servidor de nombres de dominio, utilizado para el servicio DNS.
(6) Registro TXT: almacena cualquier información de texto y se utiliza para diversos fines, como la verificación y la autenticación.
