Airgain, Inc. MAC prefix identification

A MAC address beginning with 00:1C:04 or B8:4C:87:9 matches an IEEE assignment listed to Airgain, Inc.; it does not identify a particular device or prove that Airgain made the device. The assignments comprise one 24-bit MA-L prefix and one 28-bit MA-M prefix, so each matches a different number of trailing bits in a 48-bit address.

Airgain describes itself as a provider of wireless connectivity technologies and systems for consumer, enterprise, and automotive markets. Its company overview names equipment and applications including routers, gateways, access points, set-top boxes, fleet tracking, and in-vehicle networking. These catalog categories provide company context only; the supplied sources do not connect them to either prefix.

Airgain’s November 2026 announcement describes Airgain RF Intelligence, an antenna engineering platform in development, and reports more than two decades of antenna design and integration experience. The announcement gives no mapping from that platform, its antenna portfolio, or any product to these assignments. A prefix match establishes only that the captured address falls within a registry block; it does not establish device type, shipment count, traffic prevalence, or security status.

For both listed prefixes, the first-byte Group and Local bits are zero. Under RFC 7042 guidance, these fixed bits are consistent with the assignment prefix; changing either bit yields a different prefix. The 24-bit assignment leaves 24 suffix bits, or 16,777,216 possible values; the 28-bit assignment leaves 20 suffix bits, or 1,048,576 values. These are address-space possibilities, not counts of devices or shipments.
