AceNet Technology Inc. MAC Prefix Identification
Summary
- // what this is
- AceNet Technology is registered to MAC prefix
00:18:47in the IEEE OUI database. When a device's MAC address begins with00:18:47, that block was registered by AceNet Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The exact prefix fixes the first-octet Group and Local bits at 0 and 0. The remaining 24 bits yield 16,777,216 possible suffix values; this is not an observed device count. A matching prefix indicates the registry assignment only.
About this vendor.
A MAC address beginning with 00:18:47 matches an IEEE MA-L assignment registered to AceNet Technology Inc.; the record does not identify a device category or product for that prefix.
The assignment covers the first 24 bits of a 48-bit MAC address. The remaining 24 bits allow 16,777,216 possible suffix values, but this arithmetic is not a count of devices, shipments, or addresses actually in use.
For this exact prefix, the first octet 00 has Group bit 0 and Local bit 0. RFC 7042 describes these bits as having special significance in MAC addresses. Changing either bit changes the prefix and therefore no longer matches this exact assigned value. Use the full six-octet captured address and its assignment context for identification; a prefix match establishes a registry assignment, not the device, current vendor identity, deployment, or security state.
