Which company owns MAC address prefix EC:D9:D1?

MAC address prefix EC:D9:D1 is registered to Shenzhen TG-NET Botone Technology Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:D9:D1 has a network interface built by Shenzhen TG-NET Botone Technology Co.,Ltd..

What is the OUI EC:D9:D1?

EC:D9:D1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen TG-NET Botone Technology Co.,Ltd.. It covers every address from EC:D9:D1:00:00:00 to EC:D9:D1:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-D9-D1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:D9:D1:00:00:00 that is EC:D9:D1 — 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 Shenzhen TG-NET Botone Technology Co.,Ltd. located?

Shenzhen TG-NET Botone Technology Co.,Ltd. is listed at East F/3,No.38 Huarong Second Industry Zone Shenzhen Guangdong CN 518109 in the IEEE OUI registry entry for EC:D9:D1. This is the address the organization registered with the IEEE, which may differ from its current operating address.
