FAQ
- Which company owns MAC address prefix EC:1D:9E?
- MAC address prefix EC:1D:9E is registered to Quectel Wireless Solutions Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:1D:9E has a network interface built by Quectel Wireless Solutions Co.,Ltd..
- What is the OUI EC:1D:9E?
- EC:1D:9E 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 EC:1D:9E:00:00:00 to EC:1D:9E:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-1D-9E.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in EC:1D:9E:00:00:00 that is EC:1D: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.
