Which company owns MAC address prefix E0:0E:E4?

MAC address prefix E0:0E:E4 is registered to DWnet Technologies(Suzhou) Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:0E:E4 has a network interface built by DWnet Technologies(Suzhou) Corporation.

What is the OUI E0:0E:E4?

E0:0E:E4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to DWnet Technologies(Suzhou) Corporation. It covers every address from E0:0E:E4:00:00:00 to E0:0E:E4:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-0E-E4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:0E:E4:00:00:00 that is E0:0E:E4 — 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 DWnet Technologies(Suzhou) Corporation located?

DWnet Technologies(Suzhou) Corporation is listed at No.8,Tangzhuang Road, Suzhou Industrial Park, Jiangsu, China Suzhou CN 21500 in the IEEE OUI registry entry for E0:0E:E4. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does DWnet Technologies(Suzhou) Corporation own?

DWnet Technologies(Suzhou) Corporation holds 9 OUI prefixes in the IEEE registry, of which E0:0E:E4 is one. A device made by DWnet Technologies(Suzhou) Corporation could carry a MAC address from any of them.
