where:

CPU A <character-string> which specifies the CPU type.

OS A <character-string> which specifies the operating

system type.

Standard values for CPU and OS can be found in [RFC-1010].

HINFO records are used to acquire general information about a host. The main use is for protocols such as FTP that can use special procedures when talking between machines or operating systems of the same type. ++
