Kingsignal Technology Co., Ltd. MAC Prefix Identification

A MAC address beginning with 10:93:C9 or 74:46:87 matches an IEEE MA-L assignment registered to Kingsignal Technology Co., Ltd.; the record does not identify a specific device or product. Both assignments are 24-bit prefixes, so each match covers the remaining 24 bits of an EUI-48 address.

For each listed prefix, the first octet has Group bit 0 and Local bit 0. RFC 7042 explains that these bits indicate group versus individual addressing and globally versus locally administered addressing. Turning either bit on changes the literal prefix; the fixed assigned prefixes therefore match only addresses whose first octet retains both bits as zero.

Each 24-bit suffix has 16,777,216 possible values. That is the size of the address space under each prefix, not a count of observed devices, shipments, or deployed addresses. Use the full six-octet address for an exact match; a match supports registry attribution only.

Address interpretation

Each prefix is 24 bits with Group bit 0 and Local bit 0; the remaining 24 bits allow 16,777,216 possible suffixes per prefix. [Confirmed] — https://www.rfc-editor.org/rfc/rfc7042.txt
