FAQ
- Which company owns MAC address prefix 5C:23:D6?
- MAC address prefix 5C:23:D6 is registered to China Electronics Cloud Computing Technology Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 5C:23:D6 has a network interface built by China Electronics Cloud Computing Technology Co., Ltd.
- What is the OUI 5C:23:D6?
- 5C:23:D6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to China Electronics Cloud Computing Technology Co., Ltd. It covers every address from 5C:23:D6:00:00:00 to 5C:23:D6:FF:FF:FF, or 16,777,216 addresses in total. It is also written 5C-23-D6.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in 5C:23:D6:00:00:00 that is 5C:23:D6 — 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 China Electronics Cloud Computing Technology Co., Ltd located?
- China Electronics Cloud Computing Technology Co., Ltd is listed at N3013,3F,N R&D building, A.I. Technology Park, Economic and Technological Development Zone Wuhan Hubei CN 430090 in the IEEE OUI registry entry for 5C:23:D6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
- How many MAC prefixes does China Electronics Cloud Computing Technology Co., Ltd own?
- China Electronics Cloud Computing Technology Co., Ltd holds 2 OUI prefixes in the IEEE registry, of which 5C:23:D6 is one. A device made by China Electronics Cloud Computing Technology Co., Ltd could carry a MAC address from any of them.
