Aisai Communication Technology Co., Ltd. — MAC prefix identifies registry assignment only
Summary
- // what this is
- Aisai Communication Technology is registered to MAC prefix
E0:C2:86in the IEEE OUI database. When a device's MAC address begins withE0:C2:86, that block was registered by Aisai Communication Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact match to E0:C2:86 establishes the first 24 bits of the address. Its first-byte Group and Local bits are both zero and fixed for this exact prefix. The remaining 24 bits allow 16,777,216 possible suffix values; this is not an observed device or shipment count. A prefix match does not identify a particular device or product.
About this vendor.
A MAC address beginning E0:C2:86 matches an IEEE MA-L assignment to Aisai Communication Technology Co., Ltd.; the supplied records do not identify a device or product using it.
The assignment covers the first 24 bits of a 48-bit address, leaving 24 bits for the suffix. That gives 16,777,216 possible suffix values, not a count of devices, shipments, or addresses actually in use. A match establishes the registry prefix only; it cannot identify the address’s device, operating system, current vendor identity, or security state.
The prefix’s first octet is E0 (binary 11100000). Its Group bit (bit 0) and Local bit (bit 1) are both zero. Those bits are fixed for an exact E0:C2:86 match. Setting either bit changes the prefix, so variations with those bits set are outside this literal assignment match. RFC 7042 identifies the Group and Local bits as special-significance bits in the initial octet; it says assignments use a zero Local bit and leave the Group bit unspecified.
