Introduzione al DNS:
1. Il DNS (Domain Name System, Sistema dei nomi di dominio) è un sistema distribuito, gerarchico e adattivo, che costituisce una delle infrastrutture fondamentali di Internet e serve a risolvere i nomi di dominio restituendo gli indirizzi IP ad essi associati.
2. Il DNS converte i nomi di dominio (ad esempio www.example.com) in indirizzi IP (ad esempio 192.0.2.1) che possono essere elaborati dai computer.
3. Esistono diversi tipi di query DNS:
(1) Record A: risolve il nome di dominio in un indirizzo IPv4.
(2) Record AAAA: risolve il nome di dominio in un indirizzo IPv6.
(3) Record CNAME: risolve il nome di dominio in un altro nome di dominio.
(4) Record MX: specifica il server di scambio della posta, utilizzato per il sistema di posta elettronica.
(5) Record NS: specifica il server dei nomi, utilizzato per il servizio DNS.
(6) Record TXT: memorizza informazioni di testo arbitrarie, utilizzate per vari scopi, come la verifica e l'autenticazione.
