FAQ
- Which company owns MAC address prefix B4:ED:D5?
- MAC address prefix B4:ED:D5 is registered to Quectel Wireless Solutions Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B4:ED:D5 has a network interface built by Quectel Wireless Solutions Co.,Ltd..
- What is the OUI B4:ED:D5?
- B4:ED:D5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Quectel Wireless Solutions Co.,Ltd.. It covers every address from B4:ED:D5:00:00:00 to B4:ED:D5:FF:FF:FF, or 16,777,216 addresses in total. It is also written B4-ED-D5.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in B4:ED:D5:00:00:00 that is B4:ED:D5 — 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.
