Which company owns MAC address prefix 04:E6:62?

MAC address prefix 04:E6:62 is registered to Acroname Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:E6:62 has a network interface built by Acroname Inc..

What is the OUI 04:E6:62?

04:E6:62 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Acroname Inc.. It covers every address from 04:E6:62:00:00:00 to 04:E6:62:FF:FF:FF, or 16,777,216 addresses in total. It is also written 04-E6-62.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:E6:62:00:00:00 that is 04:E6:62 — 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 Acroname Inc. located?

Acroname Inc. is listed at 4822 Sterling Drive Boulder CO US 80301-2350 in the IEEE OUI registry entry for 04:E6:62. This is the address the organization registered with the IEEE, which may differ from its current operating address.
