Which company owns MAC address prefix 68:ED:A4?

MAC address prefix 68:ED:A4 is registered to Shenzhen Seavo Technology Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:ED:A4 has a network interface built by Shenzhen Seavo Technology Co.,Ltd.

What is the OUI 68:ED:A4?

68:ED:A4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen Seavo Technology Co.,Ltd. It covers every address from 68:ED:A4:00:00:00 to 68:ED:A4:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-ED-A4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:ED:A4:00:00:00 that is 68:ED:A4 — 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 Seavo Technology Co.,Ltd located?

Shenzhen Seavo Technology Co.,Ltd is listed at 5H,West Building,NO.210,Terra Hi-Tech Industrial Park, Shenzhen Guangdong CN 518040 in the IEEE OUI registry entry for 68:ED:A4. This is the address the organization registered with the IEEE, which may differ from its current operating address.
