Which company owns MAC address prefix E4:96:AE?

MAC address prefix E4:96:AE is registered to ALTOGRAPHICS Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E4:96:AE has a network interface built by ALTOGRAPHICS Inc..

What is the OUI E4:96:AE?

E4:96:AE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ALTOGRAPHICS Inc.. It covers every address from E4:96:AE:00:00:00 to E4:96:AE:FF:FF:FF, or 16,777,216 addresses in total. It is also written E4-96-AE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E4:96:AE:00:00:00 that is E4:96:AE — 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 ALTOGRAPHICS Inc. located?

ALTOGRAPHICS Inc. is listed at Daegu Venture Center 13F Daegu KR 701-020 in the IEEE OUI registry entry for E4:96:AE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
