Which company owns MAC address prefix C8:70:D4?

MAC address prefix C8:70:D4 is registered to IBO Technology Co,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C8:70:D4 has a network interface built by IBO Technology Co,Ltd.

What is the OUI C8:70:D4?

C8:70:D4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to IBO Technology Co,Ltd. It covers every address from C8:70:D4:00:00:00 to C8:70:D4:FF:FF:FF, or 16,777,216 addresses in total. It is also written C8-70-D4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C8:70:D4:00:00:00 that is C8:70:D4 — 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 IBO Technology Co,Ltd located?

IBO Technology Co,Ltd is listed at 4F,Block.C,Unis Inforport,Langshan Rd 13,Hi-Tech Industrial Park(North)Nanshan ShenZhen GuangDong CN 518000 in the IEEE OUI registry entry for C8:70:D4. This is the address the organization registered with the IEEE, which may differ from its current operating address.
