Which company owns MAC address prefix E0:6C:F6?

MAC address prefix E0:6C:F6 is registered to ESSENCORE limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:6C:F6 has a network interface built by ESSENCORE limited.

What is the OUI E0:6C:F6?

E0:6C:F6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ESSENCORE limited. It covers every address from E0:6C:F6:00:00:00 to E0:6C:F6:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-6C-F6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:6C:F6:00:00:00 that is E0:6C:F6 — 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 ESSENCORE limited located?

ESSENCORE limited is listed at Suite 4006, 40/F Central Plaza, 18 Harbour Road, Wanchai, Hong Kong HK No code in the IEEE OUI registry entry for E0:6C:F6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
