MAC address vendor

GE Appliances MAC prefixes: vendor assignment, device unknown

Primary prefix
FC:B9:7E
Block
MA-L

Summary

// what this is
GE Appliances is registered to MAC prefix FC:B9:7E and 1 more in the IEEE OUI database. When a device's MAC address begins with FC:B9:7E, that block was registered by GE Appliances — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Both assigned prefixes are 24 bits long and have 24 suffix bits, allowing 16,777,216 possible suffix values for each; this arithmetic does not establish a device or shipment count. For these exact prefixes, the Group and Local bits of the first octet are both 0. Addresses must match the complete three-octet prefix. A match establishes the registry assignment only.

About this vendor.

Updated  ·  Confidence: High  ·  2 sources  ·  How this page is checked

A MAC address beginning with FC:B9:7E or CC:EA:27 matches an IEEE MA-L assignment to GE Appliances; the available records do not identify a device type or product for either prefix. A match identifies the registry assignment only, not a specific device, current vendor identity, deployment, or safety status.

Both assignments are 24-bit prefixes, leaving 24 bits for suffix values: 16,777,216 possible suffix values per prefix. This is a mathematical address-space count, not a count of devices or shipments. For both displayed prefixes, the first-octet Group bit is 0 and Local bit is 0. RFC 7042 explains that these bits have MAC-address significance; changing either bit yields a different literal prefix. Thus, the matching boundary is the exact first three octets shown.
