Which company owns MAC address prefix 3C:28:A6?

MAC address prefix 3C:28:A6 is registered to ALE International in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 3C:28:A6 has a network interface built by ALE International.

What is the OUI 3C:28:A6?

3C:28:A6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ALE International. It covers every address from 3C:28:A6:00:00:00 to 3C:28:A6:FF:FF:FF, or 16,777,216 addresses in total. It is also written 3C-28-A6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 3C:28:A6:00:00:00 that is 3C:28:A6 — 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 ALE International located?

ALE International is listed at 2/F, Building 1, No.60 Naxian Road,Pudong Shanghai Shanghai CN 201210 in the IEEE OUI registry entry for 3C:28:A6. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does ALE International own?

ALE International holds 3 OUI prefixes in the IEEE registry, of which 3C:28:A6 is one. A device made by ALE International could carry a MAC address from any of them.
