Acurix Networks Pty Ltd: MAC prefix identifies a registry assignment

A MAC address beginning F0:FD:A0 matches the IEEE MA-L assignment to Acurix Networks Pty Ltd. That identifies the registered prefix holder; the supplied evidence does not establish a device type, product, or which vendor made a device using a matching address.

The prefix covers the first 24 bits of a 48-bit MAC address. The remaining 24 bits allow 16,777,216 possible suffix values; this is a theoretical address space, not a device, shipment, or deployed-address count.

For the assigned prefix F0:FD:A0, the supplied address interpretation reports a Group bit value of 0 and a Local bit value of 0. RFC 7042 identifies these as the Group bit and Local bit in the initial octet of a 48-bit MAC address, and says OUIs and longer MAC prefixes are assigned with the Local bit zero and the Group bit unspecified. These registry and bit values alone do not establish deployment, traffic, current vendor identity, or security status.

The IEEE CSV record provides the legal name and MA-L assignment, but no assignment date. No company product, industry, or device category is established by the supplied evidence.

Vendor

Acurix Networks Pty Ltd is the IEEE MA-L registrant for F0:FD:A0.

Device type

Unknown; no device category is mapped to this exact prefix.

Prefix match

F0:FD:A0 matches the first 24 bits of the MAC address.

Address bits

Group bit 0 and Local bit 0 are fixed for this literal prefix; changing either bit changes the prefix.

Suffix space

24 remaining bits permit 16,777,216 possible suffix values, not an observed device count.

Assignment date

Unavailable in the displayed IEEE CSV record.
