Which company owns MAC address prefix 88:6A:E3?

MAC address prefix 88:6A:E3 is registered to Alpha Networks Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 88:6A:E3 has a network interface built by Alpha Networks Inc..

What is the OUI 88:6A:E3?

88:6A:E3 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Alpha Networks Inc.. It covers every address from 88:6A:E3:00:00:00 to 88:6A:E3:FF:FF:FF, or 16,777,216 addresses in total. It is also written 88-6A-E3.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 88:6A:E3:00:00:00 that is 88:6A:E3 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is Alpha Networks Inc. located?

Alpha Networks Inc. is listed at No.8 Li-shing 7th Rd., Science-based Industrial Park, Hsinchu, Taiwan, R.O.C Hsinchu Taiwan TW 300 in the IEEE OUI registry entry for 88:6A:E3. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Alpha Networks Inc. own?

Alpha Networks Inc. holds 9 OUI prefixes in the IEEE registry, of which 88:6A:E3 is one. A device made by Alpha Networks Inc. could carry a MAC address from any of them.
