Which company owns MAC address prefix B8:47:C6?

MAC address prefix B8:47:C6 is registered to SanJet Technology Corp. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B8:47:C6 has a network interface built by SanJet Technology Corp..

What is the OUI B8:47:C6?

B8:47:C6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SanJet Technology Corp.. It covers every address from B8:47:C6:00:00:00 to B8:47:C6:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-47-C6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B8:47:C6:00:00:00 that is B8:47:C6 — 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 SanJet Technology Corp. located?

SanJet Technology Corp. is listed at 4F,No2,Li-Hsin Rd., 6, Hsinchu TW 30078 in the IEEE OUI registry entry for B8:47:C6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
