AddPac Technology Co., Ltd. — MAC Prefix Identification
Summary
- // what this is
- AddPac Technology is registered to MAC prefix
00:02:A4in the IEEE OUI database. When a device's MAC address begins with00:02:A4, that block was registered by AddPac Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact prefix match indicates a registry assignment; it does not establish a particular device, product mapping, deployment, traffic prevalence, or security state.
About this vendor.
A MAC address beginning with 00:02:A4 matches an IEEE MA-L assignment to AddPac Technology Co., Ltd.; the record does not identify a device model or device category. The company’s overview lists network, VoIP, mobile, video, door access, smart home, IoT, IP-PBX, and CCTV equipment, as well as software. It gives April 1999 as the founding date. These company-level details do not establish which, if any, products use this prefix.
00:02:A4 is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. This is a count of possible suffixes, not a count of devices or shipments. In the first octet, 00, the Group bit is 0 and the Local bit is 0. Those bits are fixed for an exact match to this prefix; changing either bit produces a different prefix.
A match indicates the registry assignment, not a specific device, operating system, current legal identity, traffic prevalence, or security state. RFC 7042 describes MAC identifiers and these address bits.
The available IEEE CSV records show one MA-L assignment for this company and provide no assignment date. They include an address record indicating Korea; no street address is published here. The company overview URL is the source for its catalog categories and founding information.
