Types of DNS Settings

There are several types of DNS settings, including:

  • A (Address) record: Maps a domain name to an IP address.
  • MX (Mail Exchange) record: Specifies the mail server responsible for accepting email messages for a domain.
  • CNAME (Canonical Name) record: Maps an alias domain name to the real domain name.
  • NS (Name Server) record: Specifies the name servers for a domain.
  • PTR (Pointer) record: Maps an IP address to a domain name, typically used for reverse DNS lookups.
  • SOA (Start of Authority) record: Specifies the primary name server, the email of the domain administrator, and other information about a domain’s DNS.
  • SRV (Service) record: Specifies the location of a specific service, such as a voice over IP (VoIP) server, for a domain.
  • TXT (Text) record: Can be used to store any text-based information, such as SPF (Sender Policy Framework) information, for a domain.
