FAQ
- Which company owns MAC address prefix 08:3B:C1?
- MAC address prefix 08:3B:C1 is registered to Hangzhou Hikvision Digital Technology Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:3B:C1 has a network interface built by Hangzhou Hikvision Digital Technology Co.,Ltd..
- What is the OUI 08:3B:C1?
- 08:3B:C1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Hangzhou Hikvision Digital Technology Co.,Ltd.. It covers every address from 08:3B:C1:00:00:00 to 08:3B:C1:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-3B-C1.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in 08:3B:C1:00:00:00 that is 08:3B:C1 — 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 Hangzhou Hikvision Digital Technology Co.,Ltd. located?
- Hangzhou Hikvision Digital Technology Co.,Ltd. is listed at No.555 Qianmo Road Hangzhou Zhejiang CN 310052 in the IEEE OUI registry entry for 08:3B:C1. This is the address the organization registered with the IEEE, which may differ from its current operating address.
- How many MAC prefixes does Hangzhou Hikvision Digital Technology Co.,Ltd. own?
- Hangzhou Hikvision Digital Technology Co.,Ltd. holds 84 OUI prefixes in the IEEE registry, of which 08:3B:C1 is one. A device made by Hangzhou Hikvision Digital Technology Co.,Ltd. could carry a MAC address from any of them.
