# What is DNS?

DNS stands for Domain Name System. It's like a phone book for the internet that helps convert easy-to-remember website names (like www.example.com) into numbers (IP addresses) that computers use to find each other.

Key Features of a DNS Zone:

  • Zone Files
  • DNS Records
    • A: Maps a domain to an IPv4 address.
    • AAAA: Maps a domain to an IPv6 address.
    • CNAME: Aliases one domain to another.
    • MX: Specifies mail exchange servers for email delivery.
    • NS: Indicates the name servers authoritative for the zone.
  • Authority
  • Delegation
