About DNS and Whois​

  • DNS (Domain Name System): Translates human-readable domain names (like example.com) into IP addresses.
  • Whois: A query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name.

Common DNS Record Types​

  • A Record: Maps a hostname to an IPv4 address.
  • AAAA Record: Maps a hostname to an IPv6 address.
  • MX Record: Specifies the mail server responsible for accepting email messages on behalf of a domain.
  • CNAME Record: Canonical Name record, maps one domain name to another.
  • TXT Record: Allows text to be inserted into the DNS record, often used for verification (SPF, DKIM, etc.).
  • NS Record: Name Server record, indicates which DNS server is authoritative for the domain.
