FAQ
- Which company owns MAC address prefix C8:C5:0E?
- MAC address prefix C8:C5:0E is registered to Shenzhen Primestone Network Technologies.Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C8:C5:0E has a network interface built by Shenzhen Primestone Network Technologies.Co., Ltd..
- What is the OUI C8:C5:0E?
- C8:C5:0E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shenzhen Primestone Network Technologies.Co., Ltd.. It covers every address from C8:C5:0E:00:00:00 to C8:C5:0E:FF:FF:FF, or 16,777,216 addresses in total. It is also written C8-C5-0E.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in C8:C5:0E:00:00:00 that is C8:C5:0E — 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 Primestone Network Technologies.Co., Ltd. located?
- Shenzhen Primestone Network Technologies.Co., Ltd. is listed at Room 705,Complex Building, Tsinghua Hi-Tech Park Shenzhen Guangdong CN 518057 in the IEEE OUI registry entry for C8:C5:0E.
