Albrecht Jung GmbH & Co. KG: vendor assignment, device unknown

A MAC address beginning 00:22:D1 matches an IEEE MA-L assignment to Albrecht Jung GmbH & Co. KG; the assigned prefix alone does not identify a device type. The supplied registry record identifies the legal registrant, but gives no product or device mapping.

This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That is a mathematical address-space size, not a count of devices made, shipped, or observed. For this exact prefix, the first-byte Group bit is 0 and the Local bit is 0. Altering either bit changes the prefix, so these fixed bits do not imply variations within the assignment.

A captured matching address supports a prefix match to the registry entry. It cannot establish which specific device, operating system, current vendor identity, or security state is involved. Assignment dates are unavailable in these IEEE CSV records.

Registry match

Albrecht Jung GmbH & Co. KG — MA-L assignment 00:22:D1.

Device identification

Address boundary

24-bit prefix, with 24 suffix bits and 16,777,216 possible suffix values.

Interpretation

For this exact prefix, Group bit = 0 and Local bit = 0; changing either produces a different prefix.
