System Information Record (HINFO)

Allows definition of the Hardware type and Operating System (OS) in use at a host. For security reasons these records are rarely used on public servers. If a space exists in the field it must be enclosed in quotes. Single space between Hardware and OS parameters.

                IN      HINFO   PC-Intel-700mhz "Redhat Linux 7.1"

A HINFO-record specifies the host/server's type of CPU and operating system. This information can be used by application protocols such as FTP, which use special procedures when communicating with computers of a known CPU and operating system type. Standard CPU and operating system types are defined in RFC1700. To create a new HINFO-record, right-click a zone in the left list in the DNS Records window, and select "Other new record" from the pop-up menu. This record type is defined in RFC1035.
