FAQ
- Which company owns MAC address prefix B8:D8:2D?
- MAC address prefix B8:D8:2D is registered to Qingdao Intelligent&Precise Electronics Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B8:D8:2D has a network interface built by Qingdao Intelligent&Precise Electronics Co.,Ltd..
- What is the OUI B8:D8:2D?
- B8:D8:2D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Qingdao Intelligent&Precise Electronics Co.,Ltd.. It covers every address from B8:D8:2D:00:00:00 to B8:D8:2D:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-D8-2D.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in B8:D8:2D:00:00:00 that is B8:D8:2D — 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 Qingdao Intelligent&Precise Electronics Co.,Ltd. located?
