FAQ
- Which company owns MAC address prefix 9C:03:9E?
- MAC address prefix 9C:03:9E is registered to Beijing Winchannel Software Technology Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 9C:03:9E has a network interface built by Beijing Winchannel Software Technology Co., Ltd.
- What is the OUI 9C:03:9E?
- 9C:03:9E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Beijing Winchannel Software Technology Co., Ltd. It covers every address from 9C:03:9E:00:00:00 to 9C:03:9E:FF:FF:FF, or 16,777,216 addresses in total. It is also written 9C-03-9E.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in 9C:03:9E:00:00:00 that is 9C:03:9E — 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 Beijing Winchannel Software Technology Co., Ltd located?
- Beijing Winchannel Software Technology Co., Ltd is listed at 8F, Block E, Dazhongsi Zhongkun Plaza No. A Haidian District BEIJING CN 100089 in the IEEE OUI registry entry for 9C:03:9E.
