Which company owns MAC address prefix E0:30:05?

MAC address prefix E0:30:05 is registered to Alcatel-Lucent Shanghai Bell Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:30:05 has a network interface built by Alcatel-Lucent Shanghai Bell Co., Ltd.

What is the OUI E0:30:05?

E0:30:05 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Alcatel-Lucent Shanghai Bell Co., Ltd. It covers every address from E0:30:05:00:00:00 to E0:30:05:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-30-05.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:30:05:00:00:00 that is E0:30:05 — 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 Alcatel-Lucent Shanghai Bell Co., Ltd located?

Alcatel-Lucent Shanghai Bell Co., Ltd is listed at No. 389, Ningqiao Road, Pudong Jinqiao Shanghai CN 201206 in the IEEE OUI registry entry for E0:30:05. This is the address the organization registered with the IEEE, which may differ from its current operating address.
