Which company owns MAC address prefix 10:E8:64?

MAC address prefix 10:E8:64 is registered to Nucode Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:E8:64 has a network interface built by Nucode Co., Ltd..

What is the OUI 10:E8:64?

10:E8:64 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Nucode Co., Ltd.. It covers every address from 10:E8:64:00:00:00 to 10:E8:64:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-E8-64.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:E8:64:00:00:00 that is 10:E8:64 — 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 Nucode Co., Ltd. located?

Nucode Co., Ltd. is listed at 3F, Zenith Tower, 557 Yeoksam-ro Seoul KR 06182 in the IEEE OUI registry entry for 10:E8:64. This is the address the organization registered with the IEEE, which may differ from its current operating address.
