Strix Systems MAC prefixes: vendor identified, device unknown

A MAC address beginning with 00:06:5A or 00:19:33 matches an IEEE MA-L assignment to Strix Systems or Strix Systems, Inc.; the assignment does not identify a device type. The records list these as separate registrant names, so they should not be treated as proof of one legal entity or a corporate relationship.

Both are 24-bit prefixes in 48-bit MAC identifiers, leaving 24 bits for the suffix. Each therefore allows 16,777,216 possible suffix values; that is a mathematical address-space size, not a count of devices or shipments. In both prefixes, the first-byte Group bit and Local bit are zero. These bit values are fixed for an exact prefix match; changing either bit produces a different prefix.

A match establishes that the captured address begins with one of the listed registry assignments. It does not establish which device or product used it, whether the address was observed in deployment, or the registrant’s current identity or security status. The IEEE CSV records do not provide assignment dates.
