In iSCSI, there are a few options for addressing the block storage devices, with one being the iSCSI Qualified Name (IQN) that uses the domain name. But it includes a timestamp:

      -  A date code, in yyyy-mm format.  This date MUST be a date
         during which the naming authority owned the domain name used in
         this format, and SHOULD be the first month in which the domain
         name was owned by this naming authority at 00:01 GMT of the
         first day of the month.  This date code uses the Gregorian
         calendar.  All four digits in the year must be present.  Both
         digits of the month must be present, with January == "01" and
         December == "12".  The dash must be included.

Clever idea to note change of ownership situations.
