8BITDO TECHNOLOGY HK LIMITED: MAC prefix identifies an assigned vendor block
Summary
- // what this is
- 8bitdo Technology HK is registered to MAC prefix
E4:17:D8in the IEEE OUI database. When a device's MAC address begins withE4:17:D8, that block was registered by 8bitdo Technology HK — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact match to E4:17:D8 establishes a match to the MA-L assignment only; it does not identify a device, product, or deployment. For this prefix, the first-octet Group and Local bits are both zero. The 24 remaining suffix bits permit 16,777,216 possible suffix values, not a device or shipment count.
About this vendor.
A MAC address beginning E4:17:D8 matches the IEEE MA-L assignment to 8BITDO TECHNOLOGY HK LIMITED; the supplied evidence does not identify a device category or product using it. The match identifies the registered assignment, not the device’s manufacturer, current owner, operating system, deployment, or safety.
This is a 24-bit prefix, leaving 24 bits for suffix values—16,777,216 possible values. That number describes the address space available after the prefix, not a count of devices or shipments. A captured address can establish whether its first three octets match this assignment; it cannot identify a specific product from the supplied evidence.
For this exact prefix, the first octet is E4 (binary 11100100): the Group bit is 0 and the Local bit is 0. The RFC describes those bits as multicast/group and local significance; changing either bit changes the first-octet prefix and therefore no longer matches this exact assignment. The supplied records contain no assignment date.
