DNS Resource Record Types — records of the correspondence of the name and service information in the domain name system.
The most popular resource record types are:
|Address record, correspondence between name and IP address
|Canonical name for an alias (one-level redirect)
|The mail gateway address for the domain. It consists of two parts - priority (the larger the number, the lower the priority), and the host address. Critical to SMTP, the basis for Internet mail routing
|An indication of the credibility of information, used to indicate a new zone
|Record arbitrary binary data up to 255 bytes in size
