GW Technologies Co.,Ltd MAC Prefixes: Registry Assignment, Device Unknown

A MAC address beginning with D4:24:93 or 00:0F:E9 matches an IEEE MA-L assignment listed under GW Technologies Co.,Ltd; the prefix alone does not identify a specific device. The supplied records contain two /24 prefixes, each leaving 24 bits for possible suffix values. Each therefore has 16,777,216 possible suffix values, which is a mathematical address-space count, not a count of devices or shipments.

For both prefixes, the first-byte Group bit and Local bit are zero. Those bits are fixed for an exact literal prefix match. Changing either bit changes the prefix and does not describe variation within the assigned prefix. RFC 7042 explains that MAC identifiers use these bits to distinguish group and local significance; the supplied address interpretation provides their values for these particular prefixes.

The CSV records identify the registrant and give Beijing, CN addresses, supporting country-level identification as China. They provide no assignment dates, device category, product mapping, or evidence of deployment. A matching captured address supports a registry-prefix match only; it does not establish a device model, operating system, traffic prevalence, current vendor identity, or security state.
