Which company owns MAC address prefix E4:38:8C?

MAC address prefix E4:38:8C is registered to Digital Products Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E4:38:8C has a network interface built by Digital Products Limited.

What is the OUI E4:38:8C?

E4:38:8C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Digital Products Limited. It covers every address from E4:38:8C:00:00:00 to E4:38:8C:FF:FF:FF, or 16,777,216 addresses in total. It is also written E4-38-8C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E4:38:8C:00:00:00 that is E4:38:8C — 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 Digital Products Limited located?

Digital Products Limited is listed at 53 Clark Road Rothesay New Brunswick CA E2E 2K9 in the IEEE OUI registry entry for E4:38:8C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
