Advantage Century Telecommunication Corp. MAC prefix identification
Summary
- // what this is
- Advantage Century Telecommunication is registered to MAC prefix
00:D0:E9in the IEEE OUI database. When a device's MAC address begins with00:D0:E9, that block was registered by Advantage Century Telecommunication — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The 24-bit prefix fixes the first-byte Group bit at 0 and Local bit at 0; changing either bit creates a different prefix. The remaining 24 bits allow 16,777,216 possible suffix values, not an observed device or shipment count.
About this vendor.
A MAC address beginning 00:D0:E9 matches an IEEE MA-L assignment registered to Advantage Century Telecommunication Corp.; the record does not identify a device category or product. A matching prefix establishes the registry assignment for the address range, not the identity, deployment, or safety of a particular device.
This is a 24-bit prefix, leaving 24 bits for the address suffix. That allows 16,777,216 possible suffix values; it is a mathematical range size, not a count of devices or shipments. In the first octet, 00 has Group bit 0 and Local bit 0. Those bits are fixed for this exact prefix; changing either produces a different prefix.
RFC 7042 describes 48-bit MAC identifiers as an assigned initial prefix followed by additional bits, and explains the Group and Local bits. The IEEE record lists Advantage Century Telecommunication Corp. at an address in Taipei, with the country code TW; this is registry address information and does not establish current headquarters or operating country. The supplied CSV records do not provide assignment dates.
