A MAC address is a unique identifier given to a network card when it is manufactured. It can be written in the format MM:MM:MM:UU:UU:UU, where M represents a standard vendor ID (also referred to as an OUI, or Organizationally Unique Identifier)  and U represents a unique identifier for that device.  APC Network devices originally used 00 C0 B7 as the vendor ID, however newer networked devices will be changing that section. 

The limit of unique identifiers has been reached in the "00:C0:B7" MAC address range, so a new ID of "28:29:86" is being used. Network protocols that use MAC address (such as static IP addresses configured via DHCP, or the 802.1x protocol MAC bypass) would need to be updated to include the new APC vendor prefix. Units manufactured in late Q4 2017 will have the new MAC prefix.

The APC Device IP configuration wizard uses the MAC address to identify unconfigured APC network cards. Older revisions of the wizard will not work with cards that use the new vendor ID; IP config wizard v5.0.3 and higher support both vendor ID's.
