ADVANCED HI-TECH CORP. — MAC prefix identifies a registry assignment; device type Unknown
Summary
- // what this is
- Advanced Hi-Tech is registered to MAC prefix
00:50:74in the IEEE OUI database. When a device's MAC address begins with00:50:74, that block was registered by Advanced Hi-Tech — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A matching MAC prefix indicates an IEEE registry assignment, not a specific device or deployment. The first-byte Group and Local bits are both zero for this exact prefix; the 24-bit suffix permits 16,777,216 possible values, not a device or shipment count. Changing either bit yields a different prefix.
About this vendor.
A MAC address beginning 00:50:74 matches an IEEE MA-L assignment registered to ADVANCED HI-TECH CORP. The supplied evidence does not identify a device category or a particular product that uses this prefix, so the device type is Unknown.
This is one 24-bit prefix, leaving 24 bits for the suffix. The Group and Local bits in its first byte are both zero. A capture matching the prefix can establish that the address begins with this assigned value; it cannot identify a specific device, operating system, deployment, or current vendor identity.
RFC 7042 explains that 48-bit MAC identifiers can use an initial OUI or a longer assigned prefix, with remaining bits available for assignment. The 24-bit suffix has 16,777,216 possible values, a mathematical address-space count rather than a device or shipment count. A change to either fixed first-byte bit produces a different prefix and is not variation within this assignment.
