Mindray Co., Ltd.: two IEEE MA-L prefix assignments
Summary
- // what this is
- Mindray is registered to MAC prefix
00:0F:14and 1 more in the IEEE OUI database. When a device's MAC address begins with00:0F:14, that block was registered by Mindray — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact prefix match indicates an IEEE registry assignment only; it does not identify a particular device, establish deployment, or indicate security state.
About this vendor.
A MAC address beginning with 00:0F:14 or 38:0B:26 matches an IEEE MA-L assignment registered to Mindray Co., Ltd.; that match identifies the registry record, not a particular device or product. The supplied evidence does not establish a device category for either prefix.
Both assignments are 24-bit prefixes, leaving 24 bits for suffix values. Each therefore has 16,777,216 possible suffix values; this is a mathematical range, not a count of devices or shipments. For both exact prefixes, the first-octet Group bit is 0 and the Local bit is 0. The matching boundary is the first 24 bits: changing either bit changes the prefix and no longer matches that exact assignment.
RFC 7042 describes 48-bit MAC identifiers as an assigned initial prefix followed by additional bits, and explains the Group and Local bits. These CSV records show two entries under the same legal name, but do not provide assignment dates. They do not establish current vendor identity, actual deployment, traffic prevalence, or safety.
- Registry match
- Mindray Co., Ltd. —
00:0F:14and38:0B:26are MA-L assignments. - Device class
- Unknown; no supplied source maps a device category to these exact prefixes.
- Prefix length
- 24 bits each, leaving 24 suffix bits per prefix.
- Bit interpretation
- Group bit 0 and Local bit 0 for both exact prefixes; changing either changes the prefix match.
