Which company owns MAC address prefix 18:6B:E2?

MAC address prefix 18:6B:E2 is registered to LYLINK LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 18:6B:E2 has a network interface built by LYLINK LIMITED.

What is the OUI 18:6B:E2?

18:6B:E2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to LYLINK LIMITED. It covers every address from 18:6B:E2:00:00:00 to 18:6B:E2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 18-6B-E2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 18:6B:E2:00:00:00 that is 18:6B:E2 — 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 LYLINK LIMITED located?

LYLINK LIMITED is listed at RM 511, 5/F, MING SANG IND BLDG, 19-21 HING YIP STREET, KWUN TONG，HONG KONG HONGKONG HK 999077 in the IEEE OUI registry entry for 18:6B:E2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
