Shenzhen Sang Fei Consumer Communications Co.,Ltd: MAC prefix identification
Summary
- // what this is
- Shenzhen Sang Fei Consumer Communications is registered to MAC prefix
00:1D:07and 1 more in the IEEE OUI database. When a device's MAC address begins with00:1D:07, that block was registered by Shenzhen Sang Fei Consumer Communications — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The two exact 24-bit prefixes each leave 24 suffix bits (16,777,216 possible values). Their first-byte Group and Local bits are zero; changing either bit changes the matched prefix. Possible suffix values do not indicate actual device or shipment counts. A match establishes a registry assignment only.
About this vendor.
A MAC address beginning with 00:1D:07 or 9C:E9:51 matches an MA-L assignment registered to Shenzhen Sang Fei Consumer Communications Co.,Ltd or a closely named registrant. This identifies the registry match; it does not establish a device category, a particular product, or who currently operates the device.
Both assignments are 24-bit prefixes, leaving 24 bits for the suffix. Each therefore has 16,777,216 possible suffix values. That is an address-space calculation, not a count of devices, shipments, or addresses observed in use.
For both exact prefixes, the first-byte Group bit and Local bit are zero. RFC 7042 describes these bits as significant in MAC identifiers: setting either bit changes the first octet and therefore no longer matches this exact prefix. Treat a match as evidence of the assigned prefix only; it does not establish deployment or prevalence.
- Registry match
- Shenzhen Sang Fei Consumer Communications Co.,Ltd — MA-L assignment.

00:1D:07and9C:E9:51.- Interpretation
- Each is a 24-bit prefix with 24 suffix bits; the Group and Local bits are zero in both exact first octets.
