Which company owns MAC address prefix EC:DB:86?

MAC address prefix EC:DB:86 is registered to API-K in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:DB:86 has a network interface built by API-K.

What is the OUI EC:DB:86?

EC:DB:86 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to API-K. It covers every address from EC:DB:86:00:00:00 to EC:DB:86:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-DB-86.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:DB:86:00:00:00 that is EC:DB:86 — 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 API-K located?

API-K is listed at ZA Tire Poix Saint Vincent de Mercuze Isère FR 38660 in the IEEE OUI registry entry for EC:DB:86. This is the address the organization registered with the IEEE, which may differ from its current operating address.
