Which company owns MAC address prefix 7C:6A:DB?

MAC address prefix 7C:6A:DB is registered to SafeTone Technology Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 7C:6A:DB has a network interface built by SafeTone Technology Co.,Ltd.

What is the OUI 7C:6A:DB?

7C:6A:DB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SafeTone Technology Co.,Ltd. It covers every address from 7C:6A:DB:00:00:00 to 7C:6A:DB:FF:FF:FF, or 16,777,216 addresses in total. It is also written 7C-6A-DB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 7C:6A:DB:00:00:00 that is 7C:6A: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 SafeTone Technology Co.,Ltd located?

SafeTone Technology Co.,Ltd is listed at Room 323,ZhuouJi Plaza,No.16 AnDe Road,East District, Beijing CN 100011 in the IEEE OUI registry entry for 7C:6A:DB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
