Advidia MAC prefix 78:A1:83: vendor identified; device type unknown

A MAC address beginning 78:A1:83 matches an IEEE MA-L assignment to Advidia. That identifies the registered assignment holder, but does not establish which device, if any, used the address. No supplied retrieved material documents Advidia’s products, industry, or current legal identity, so those details are unknown here.

The assignment covers the first 24 bits of a 48-bit MAC address. The Group and Local bits in the first byte 78 are both zero. They are fixed for this exact prefix; changing either bit produces a different prefix. The remaining 24 bits allow 16,777,216 possible suffix values, not a count of devices or shipments.

A captured address matching this prefix supports an assignment match only. It cannot establish deployment, traffic prevalence, a particular product or operating system, or security status. The supplied IEEE CSV record does not display an assignment date.
