Advanced Television Systems Committee, Inc. — vendor identified by one MA-L assignment
Summary
- // what this is
- Advanced Television Systems Committee is registered to MAC prefix
00:09:79in the IEEE OUI database. When a device's MAC address begins with00:09:79, that block was registered by Advanced Television Systems Committee — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A literal
00:09:79match fixes the first octet's Group bit at 0 and Local bit at 0; changing either bit yields a different prefix. The 24-bit suffix has 16,777,216 possible values, not an observed device or shipment count. A match indicates registry assignment only, not a particular device, operating system, current legal identity, or security state.
About this vendor.
A MAC address beginning 00:09:79 matches an MA-L assignment registered to Advanced Television Systems Committee, Inc.; the record does not identify a device category or product that uses it.
The assignment is 24 bits long, leaving 24 bits in a 48-bit address. This permits 16,777,216 possible suffix values within the prefix. That arithmetic describes address space, not a count of devices, deployments, or shipments.
The supplied RFC 7042 passage names the Group bit (01) and Local bit (02) in the initial octet, and says OUIs and longer MAC prefixes are assigned with the Local bit zero and the Group bit unspecified. For the assigned prefix 00:09:79, the first-octet values make both bits zero. The IEEE assignment gives a 24-bit prefix, leaving a 24-bit suffix in a 48-bit address.
A matching address establishes a prefix match; the supplied evidence does not establish device identity, operating system, present owner, or security state.
