ALARIS MEDICAL SYSTEMS, INC. — MAC prefix identification
Summary
- // what this is
- Alaris Medical Systems is registered to MAC prefix
00:D0:75in the IEEE OUI database. When a device's MAC address begins with00:D0:75, that block was registered by Alaris Medical Systems — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The 24-bit prefix leaves 24 suffix bits (16,777,216 possible values). For exact prefix 00:D0:75, the first-octet Group and Local bits are both zero; either bit changing produces a different prefix. A match establishes the registry prefix only, not a particular device, deployment, traffic prevalence, or safety state.
About this vendor.
A MAC address beginning 00:D0:75 matches an IEEE MA-L assignment registered to ALARIS MEDICAL SYSTEMS, INC.; the record does not identify a device type or product. The match identifies the assignment only, not a particular device, its maker, deployment, or security status.
The assignment covers the first 24 bits of a 48-bit MAC identifier, leaving 24 suffix bits, or 16,777,216 possible suffix values. That is a mathematical address space, not a count of devices or shipments. A registry prefix match alone does not establish deployment or prevalence.
For this exact prefix, the first octet 00 has Group bit 0 and Local bit 0. These bits are fixed in the literal prefix: changing either changes the prefix and no longer matches 00:D0:75. RFC 7042 describes how these bits distinguish group and individual addressing and explains 48-bit MAC identifiers and their prefixes. The supplied IEEE record includes no assignment date.
