Which company owns MAC address prefix DC:EB:5D?

MAC address prefix DC:EB:5D is registered to Shandong Sinochip Semiconductors Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with DC:EB:5D has a network interface built by Shandong Sinochip Semiconductors Co.,Ltd..

What is the OUI DC:EB:5D?

DC:EB:5D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shandong Sinochip Semiconductors Co.,Ltd.. It covers every address from DC:EB:5D:00:00:00 to DC:EB:5D:FF:FF:FF, or 16,777,216 addresses in total. It is also written DC-EB-5D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in DC:EB:5D:00:00:00 that is DC:EB:5D — 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 Shandong Sinochip Semiconductors Co.,Ltd. located?

Shandong Sinochip Semiconductors Co.,Ltd. is listed at 210A, Building A2-3, HanYu Finance Valley, No.7000, Jingshi East Road, High Tech District, Jinan, Shandong Province, P.R.C Jinan Shandong CN 250101 in the IEEE OUI registry entry for DC:EB:5D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
