Updated · Confidence: High · 2 sources · How this page is checked
A MAC address beginning with BC:0F:B7 or 5C:64:F3 is registered to sywinkey HongKong Co,. Limited? ; the supplied records do not identify a device category or product. Both entries are MA-L assignments with 24-bit prefixes, leaving 24 bits for the remaining address. An exact prefix match supports identifying the IEEE registry assignee only. It does not establish which device made the address, whether that device is deployed, or how common it is.
The two assignments are listed separately, so treat each prefix as its own registry match.
