Which company owns MAC address prefix E8:F2:E3?

MAC address prefix E8:F2:E3 is registered to Starcor Beijing Co.,Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E8:F2:E3 has a network interface built by Starcor Beijing Co.,Limited.

What is the OUI E8:F2:E3?

E8:F2:E3 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Starcor Beijing Co.,Limited. It covers every address from E8:F2:E3:00:00:00 to E8:F2:E3:FF:FF:FF, or 16,777,216 addresses in total. It is also written E8-F2-E3.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E8:F2:E3:00:00:00 that is E8:F2:E3 — 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 Starcor Beijing Co.,Limited located?

Starcor Beijing Co.,Limited is listed at NO.210 Block B, Building 2 Beijing Berijing CN 100089 in the IEEE OUI registry entry for E8:F2:E3. This is the address the organization registered with the IEEE, which may differ from its current operating address.
