Which company owns MAC address prefix EC:71:DB?

MAC address prefix EC:71:DB is registered to Reolink Innovation Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:71:DB has a network interface built by Reolink Innovation Limited.

What is the OUI EC:71:DB?

EC:71:DB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Reolink Innovation Limited. It covers every address from EC:71:DB:00:00:00 to EC:71:DB:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-71-DB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:71:DB:00:00:00 that is EC:71:DB — 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 Reolink Innovation Limited located?

Reolink Innovation Limited is listed at 705,7/F,FA YUEN COMMERCIAL BUILDING,75-77 FA YUEN STREET MONG KOK KL CN 999077 in the IEEE OUI registry entry for EC:71:DB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
