Additech, Inc. MAC Prefix: Vendor Identified, Device Unknown
Summary
- // what this is
- Additech is registered to MAC prefix
C0:0D:7Ein the IEEE OUI database. When a device's MAC address begins withC0:0D:7E, that block was registered by Additech — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A match identifies the MA-L registry assignment only. The 24-bit suffix has 16,777,216 possible values, not an observed device or shipment count. For this literal prefix, the first-octet Group and Local bits are both zero; changing either bit yields a different prefix.
About this vendor.
A MAC address beginning with C0:0D:7E matches an IEEE MA-L assignment to Additech, Inc.; the assignment does not identify a device category or prove that a particular device is using it. The registry record indicates the United States, but supplies no assignment date. No company product or industry information is present in the supplied evidence.
This is a 24-bit prefix, so matching compares the first three octets, C0:0D:7E, of a 48-bit MAC address. The remaining 24 bits allow 16,777,216 possible suffix values; that number describes address space, not devices, shipments, or observed traffic. RFC 7042 describes 48-bit MAC identifiers and the significance of the Group and Local bits. For this exact prefix, both bits are zero in the first octet C0.
They are fixed for a literal prefix match; changing either bit produces a different prefix. A match establishes a registry assignment only, not a specific product, current legal identity, or security state.
