FAQ
- Which company owns MAC address prefix C0:E5:DA?
- MAC address prefix C0:E5:DA is registered to Qingdao Intelligent&Precise Electronics Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C0:E5:DA has a network interface built by Qingdao Intelligent&Precise Electronics Co.,Ltd..
- What is the OUI C0:E5:DA?
- C0:E5:DA 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 C0:E5:DA:00:00:00 to C0:E5:DA:FF:FF:FF, or 16,777,216 addresses in total. It is also written C0-E5-DA.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in C0:E5:DA:00:00:00 that is C0:E5:DA — 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?
- Qingdao Intelligent&Precise Electronics Co.,Ltd. is listed at No.218 Qianwangang Road Qingdao Shangdong CN 266510 in the IEEE OUI registry entry for C0:E5:DA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
- How many MAC prefixes does Qingdao Intelligent&Precise Electronics Co.,Ltd. own?
- Qingdao Intelligent&Precise Electronics Co.,Ltd. holds 22 OUI prefixes in the IEEE registry, of which C0:E5:DA is one. A device made by Qingdao Intelligent&Precise Electronics Co.,Ltd. could carry a MAC address from any of them.
