ADNACOM INC. MAC Prefix 4C:0A:3D — vendor known, device type unknown
Summary
- // what this is
- Adnacom is registered to MAC prefix
4C:0A:3Din the IEEE OUI database. When a device's MAC address begins with4C:0A:3D, that block was registered by Adnacom — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The 24-bit MA-L prefix 4C:0A:3D fixes the first-octet Group and Local bits at 0; 24 suffix bits allow 16,777,216 possible values. This is an address-space count, not an observed device or shipment count. A matching address indicates a registry assignment match only.
About this vendor.
A MAC address beginning with 4C:0A:3D matches an IEEE MA-L assignment to ADNACOM INC.; the available evidence does not identify a device category or product using it. This identifies the registered prefix holder, not the manufacturer of a particular observed device or its current operator.
The MA-L assignment covers 24 bits of a 48-bit MAC address, leaving 24 bits after the prefix. The first octet 4C has Group bit 0 and Local bit 0. RFC 7042 identifies the Group and Local bits as having special significance in MAC addresses; for this exact prefix, both are fixed at zero. Changing either bit produces a different prefix, rather than a variation within this assignment.
There are 16,777,216 possible suffix values after this prefix, a mathematical address-space count rather than a device, shipment, or deployment count. A captured address with this prefix supports a registry-prefix match only. Assignment dates are unavailable in these IEEE CSV records.
