MAC address vendor
Algorab S.r.l. MAC Prefix 90:27:2B — Vendor Known, Device Unknown
Primary prefix
90:27:2B
Block
MA-L
Summary
- // what this is
- Algorab is registered to MAC prefix
90:27:2Bin the IEEE OUI database. When a device's MAC address begins with90:27:2B, that block was registered by Algorab — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- This 24-bit prefix leaves 24 bits for 16,777,216 possible suffix values; this is an address-space count, not a device or shipment count. For the exact prefix, the first-octet Group and Local bits are both zero. Changing either bit produces a different prefix match. RFC 7042 provides MAC address interpretation guidance.

A MAC address beginning with 90:27:2B matches an IEEE MA-L assignment to Algorab S.r.l.; the supplied records do not identify a device category for this prefix. The assignment is a registry record, not evidence that a particular captured address is deployed by the company or associated with a specific product, operating system, or security state.
This is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That is a mathematical address-space count, not a count of devices, shipments, or observed traffic. RFC 7042 describes the Group and Local bits in the first octet; for this exact prefix, both are zero. Changing either bit changes the prefix match, rather than varying an address within this fixed assignment.
