About this vendor.
Updated · Confidence: High · 2 sources · How this page is checked
The prefixes 4C:BC:72 and 00:1E:B3 are both registered to Primex Wireless. In each prefix, the Group bit is 0 and the Local bit is 0.
RFC 7042 explains that these bits distinguish group and local addressing; changing either bit produces a different prefix, rather than a variation within the fixed assignment. Each 24-bit prefix leaves 24 suffix bits, allowing 16,777,216 possible suffix values. That is an address-space count, not a device or shipment count. A prefix match establishes a registry assignment, not observed use, current vendor identity, or security state. The records provide no assignment dates.
