Which company owns MAC address prefix BC:E0:9D?

MAC address prefix BC:E0:9D is registered to Eoslink in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with BC:E0:9D has a network interface built by Eoslink.

What is the OUI BC:E0:9D?

BC:E0:9D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Eoslink. It covers every address from BC:E0:9D:00:00:00 to BC:E0:9D:FF:FF:FF, or 16,777,216 addresses in total. It is also written BC-E0-9D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in BC:E0:9D:00:00:00 that is BC:E0:9D — 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 Eoslink located?

Eoslink is listed at #602, 900-1 Anyang-City Kyonggi-Do KR 431-060 in the IEEE OUI registry entry for BC:E0:9D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
