ABL CANADA, INC. MAC prefix: vendor identification unknown
Summary
- // what this is
- ABL Canada is registered to MAC prefix
00:50:1Bin the IEEE OUI database. When a device's MAC address begins with00:50:1B, that block was registered by ABL Canada — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The exact 24-bit prefix has Group bit 0 and Local bit 0 in its first octet. The remaining 24 bits yield 16,777,216 possible suffix values, which is not an observed device or shipment count. A literal match establishes only the registered prefix.
About this vendor.
A MAC address beginning 00:50:1B matches the IEEE MA-L assignment registered to ABL CANADA, INC.; the supplied records do not identify a device category or product using it. The match identifies the registered prefix only, not the device, its maker, current ownership, or safety.
The assigned 24-bit prefix leaves 24 bits for suffix values, or 16,777,216 possible values. That is a mathematical address-space count, not an observed number of devices, products, or shipments. RFC 7042 describes EUI-48 identifiers as an assigned initial prefix followed by additional bits, and explains the Group and Local bits in the first octet.
For this exact prefix, both first-octet bits are zero: 00 has Group bit 0 and Local bit 0. Those bits are fixed by the literal prefix. Flipping either bit changes the prefix, so such an address no longer matches this exact assignment. A captured MAC can establish a prefix match, but not an individual device identity or deployment history.
