HINFO (host information) resource record

HINFO (host information) resource record

HINFO records contain host-specific data. They list the hardware and operating system that are running at the listed host. If you want to include a space in the machine name, you must quote the name. Host information is not specific to any address class, so ANY may be used for the address class. There should be one HINFO record for each host. For security reasons, many sites do not include the HINFO record, and no applications depend on this record. Here is an example:

   {name}   {ttl}   addr-class   HINFO   Hardware     OS
                    ANY          HINFO   Intel i486   UNIX
