00:40:08 — A PLUS INFO CORPORATION
Summary
- // what this is
- A PLUS INFO is registered to MAC prefix
00:40:08in the IEEE OUI database. When a device's MAC address begins with00:40:08, that block was registered by A PLUS INFO — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact match fixes the first-octet Group and Local bits at zero; changing either bit yields a different prefix. The 24-bit prefix leaves 24 suffix bits, allowing 16,777,216 possible values, not a device or shipment count. A prefix match establishes a registry assignment only.
About this vendor.
A MAC address beginning 00:40:08 matches an IEEE MA-L assignment to A PLUS INFO CORPORATION. The assignment identifies the registry holder; the available evidence does not identify a device category, product, or deployment using this prefix. A matching address alone cannot establish the device, its current operator, or its security state.
This is a 24-bit prefix, leaving 24 bits in a 48-bit address. The IEEE record lists one assignment, 00:40:08, and provides no assignment date. Its address record indicates Taiwan. No supplied first-party evidence establishes the company’s industry, product catalog, or website.
The first octet is 00 (binary 00000000): its Group bit (bit 0) and Local bit (bit 1) are both zero. These values are fixed for an exact match to this prefix; changing either bit produces a different prefix. A matching boundary requires the first 24 bits to match. The remaining 24 bits allow 16,777,216 possible suffix values, not a count of devices or shipments. RFC 7042 describes the relationship between MAC prefixes and identifiers.
