Which company owns MAC address prefix 34:7E:CA?

MAC address prefix 34:7E:CA is registered to NEXTWILL in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 34:7E:CA has a network interface built by NEXTWILL.

What is the OUI 34:7E:CA?

34:7E:CA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NEXTWILL. It covers every address from 34:7E:CA:00:00:00 to 34:7E:CA:FF:FF:FF, or 16,777,216 addresses in total. It is also written 34-7E-CA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 34:7E:CA:00:00:00 that is 34:7E:CA — 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 NEXTWILL located?

NEXTWILL is listed at JJ-Building, 20, Deongmyeong-ro 71beon-gil1, Yuseong-gu Daejeon KR 34155 in the IEEE OUI registry entry for 34:7E:CA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
