Pepwave Limited MAC prefixes: device type Unknown

A MAC address beginning with A8:C0:EA is assigned in the IEEE MA-L registry to Pepwave Limited. A MAC beginning with 00:1A:DD is assigned to the separately named registrant PePWave Ltd. The records do not identify a device category for either prefix, so a prefix match cannot establish what device made the address.

Both prefixes are 24 bits long, leaving 24 bits for suffix values. The first-byte Group and Local bits are zero for each exact prefix. Setting either bit changes the prefix and is not variation within that assignment. Each prefix allows 16,777,216 possible suffix values; that is an address-space calculation, not a count of devices or shipments. The records give Hong Kong addresses and no assignment dates. RFC 7042 describes MAC prefix structure and the Group and Local bits.

Device class

Unknown; the records do not map either prefix to a device category.

IEEE registrants

Pepwave Limited (A8:C0:EA) and PePWave Ltd (00:1A:DD), listed as separate registrant names.

Country

Hong Kong, indicated in both IEEE record addresses.

Registry

MA-L; 2 full prefixes.

Interpretation

Each /24 prefix has 24 suffix bits, or 16,777,216 possible suffix values. Both prefixes have Group bit 0 and Local bit 0; changing either bit produces a different prefix.
