Which company owns MAC address prefix F0:DE:71?

MAC address prefix F0:DE:71 is registered to Shanghai EDO Technologies Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with F0:DE:71 has a network interface built by Shanghai EDO Technologies Co.,Ltd..

What is the OUI F0:DE:71?

F0:DE:71 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Shanghai EDO Technologies Co.,Ltd.. It covers every address from F0:DE:71:00:00:00 to F0:DE:71:FF:FF:FF, or 16,777,216 addresses in total. It is also written F0-DE-71.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in F0:DE:71:00:00:00 that is F0:DE:71 — 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 Shanghai EDO Technologies Co.,Ltd. located?

Shanghai EDO Technologies Co.,Ltd. is listed at Unit 12302, Building 12,498 Guoshoujing Road, Pudong New Area Shanghai CN 201203 in the IEEE OUI registry entry for F0:DE:71. This is the address the organization registered with the IEEE, which may differ from its current operating address.
