Which company owns MAC address prefix E0:E6:31?

MAC address prefix E0:E6:31 is registered to SNB TECHNOLOGIES LIMITED in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:E6:31 has a network interface built by SNB TECHNOLOGIES LIMITED.

What is the OUI E0:E6:31?

E0:E6:31 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SNB TECHNOLOGIES LIMITED. It covers every address from E0:E6:31:00:00:00 to E0:E6:31:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-E6-31.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:E6:31:00:00:00 that is E0:E6:31 — 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 SNB TECHNOLOGIES LIMITED located?

SNB TECHNOLOGIES LIMITED is listed at Rm 303, Building #13, Long Gang district, ShenZhen GuangDong CN 518000 in the IEEE OUI registry entry for E0:E6:31. This is the address the organization registered with the IEEE, which may differ from its current operating address.
