ABB n.v. Power Quality Products — MAC prefix identification

A MAC address beginning 98:03:A0 matches an IEEE MA-L assignment to ABB n.v. Power Quality Products; the record does not identify a specific device or product. The assignment is 24 bits long, leaving 24 bits for possible suffix values. IEEE registry attribution establishes the registered organization for this prefix, not which device used an observed address or whether it is currently deployed.

In the first octet, 98 has Group bit 0 and Local bit 0. Those bits are fixed for this exact prefix. A change to either bit produces a different prefix, so their values should not be treated as variation within the assignment. A full 48-bit address can match this assigned prefix when its first three octets are 98:03:A0; the remaining three octets can take 16,777,216 possible values, not evidence of that many devices or shipments.

RFC 7042 describes 48-bit MAC identifiers as an initial assigned prefix followed by additional bits, and explains the Group and Local bits. Company products, industry, country, website, and device categories: Unknown. Assignment date: Unknown.
