Mako Networks Ltd MAC prefixes: vendor identified, device unknown
Summary
- // what this is
- Mako Networks is registered to MAC prefix
30:1A:28and 1 more in the IEEE OUI database. When a device's MAC address begins with30:1A:28, that block was registered by Mako Networks — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
About this vendor.
A MAC address beginning with 30:1A:28 or 30:1A:30 matches an IEEE MA-L assignment registered to Mako Networks Ltd; the assignment alone does not identify a device or product. No supplied evidence maps either prefix to a device category or a specific product.
Both are 24-bit prefixes, leaving 24 bits for the remaining address: 16,777,216 possible suffix values per prefix. For each exact prefix, the first octet is 30 (binary 00110000): its Group bit and Local bit are both zero, consistent with a globally administered individual address. Changing either bit would yield a different prefix, not a variation within that exact assignment. The suffix possibilities are a mathematical range, not a count of devices or shipments.
RFC 7042 explains that a 48-bit MAC identifier can contain an initial three-octet OUI followed by three additional octets. A matching captured address supports the registry-prefix match only; it does not establish the device, operating system, deployment, traffic prevalence, current vendor identity, or security state.
