SHENZHEN TONG BO WEI TECHNOLOGY: MAC prefix identification
Summary
- // what this is
- Shenzhen TONG BO WEI Technology is registered to MAC prefix
E0:09:BFand 1 more in the IEEE OUI database. When a device's MAC address begins withE0:09:BF, that block was registered by Shenzhen TONG BO WEI Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- RFC 7042 describes 48-bit MAC identifiers as an initial OUI or longer organizational prefix plus additional bits; the Group and Local bits have special significance. The two prefixes each leave 24 suffix bits, or 16,777,216 possible suffix values.
About this vendor.
A MAC address beginning with E0:09:BF or 28:AD:3E matches an IEEE MA-L assignment to SHENZHEN TONG BO WEI TECHNOLOGY Co.,LTD. The records identify the registrant; they do not establish which device or product used a matching address.
Both assignments are 24-bit prefixes in 48-bit MAC identifiers, leaving 24 suffix bits, or 16,777,216 possible suffix values per prefix. This is an address-space count, not a count of devices, shipments, or addresses observed in use.
For each listed prefix, the first-octet Group bit and Local bit are both zero. These values are fixed by the literal prefix: changing either bit produces a different prefix. A matching address therefore supports identification of the registry assignment, but does not by itself identify a device class, deployment, traffic prevalence, current vendor identity, or security status.
The IEEE CSV excerpts provide no assignment dates. RFC 7042 describes the structure and interpretation of 48-bit MAC identifiers and the significance of the Group and Local bits.
