Which company owns MAC address prefix 30:F7:7F?

MAC address prefix 30:F7:7F is registered to S Mobile Devices Limited in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 30:F7:7F has a network interface built by S Mobile Devices Limited.

What is the OUI 30:F7:7F?

30:F7:7F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to S Mobile Devices Limited. It covers every address from 30:F7:7F:00:00:00 to 30:F7:7F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 30-F7-7F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 30:F7:7F:00:00:00 that is 30:F7:7F — 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 S Mobile Devices Limited located?
