80:7A:7F identifies an IEEE assignment to ABB Genway Xiamen Electrical Equipment CO., LTD
Summary
- // what this is
- ABB Genway Xiamen Electrical Equipment is registered to MAC prefix
80:7A:7Fin the IEEE OUI database. When a device's MAC address begins with80:7A:7F, that block was registered by ABB Genway Xiamen Electrical Equipment — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A match establishes the IEEE registry assignment for the 24-bit prefix, not device identity, deployment, or prevalence. The 24 remaining bits allow 16,777,216 suffix values; this is not a device or shipment count. In first octet 0x80, Group and Local bits are both zero. These bits are fixed for this exact prefix; flipping either changes the prefix. RFC 7042 explains MAC identifier and prefix conventions.
About this vendor.
A MAC address beginning 80:7A:7F matches an IEEE MA-L assignment registered to ABB Genway Xiamen Electrical Equipment CO., LTD. The record identifies the assignee; it does not establish a device type, a particular product, current vendor identity, or who deployed a captured interface. The registration record gives China as the country.
The match covers the first 24 bits, or three octets. The remaining 24 bits allow 16,777,216 possible suffix values; that is a mathematical address space, not a count of devices or shipments. For this exact prefix, the first octet is 0x80: its Group bit and Local bit are both 0. Changing either bit creates a different prefix; the bits do not vary within this fixed assignment. RFC 7042 describes these MAC identifier and prefix conventions.
