Description

  • A record is the most commonly used type, directing a domain name to an IPv4 address, such as 8.8.8.8.
  • CNAME directs a domain name to another domain name address, maintaining the same resolution.
  • MX is used for mail servers, with relevant parameters typically provided by the mail registrar.
  • TXT allows for additional text information to be filled in, commonly used for domain verification.
  • AAAA directs a domain name to an IPv6 address, such as 2404:6800:4012:3::200e.
  • NS is a domain name server record that can delegate a specified domain to other DNS service providers for resolution management.
  • CAA is used to specify the Certificate Authority (CA) for a domain, reducing certificate issuance risks.
  • SRV identifies a server using a specific service, commonly found in Microsoft systems for directory management. The format is "service name.protocol type," such as _sip._tcp.
  • HTTPS is an HTTPS service binding record that helps enhance HTTPS security and performance.
  • SVCB is a new type of service binding record that allows services to point to multiple clients and associate with custom parameter values.
