What is the OUI 34:97:6F?

34:97:6F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Rootech, Inc.. It covers every address from 34:97:6F:00:00:00 to 34:97:6F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 34-97-6F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 34:97:6F:00:00:00 that is 34:97:6F — 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 Rootech, Inc. located?

Rootech, Inc. is listed at 102-611 Digital Empire2, 88, Sin won-ro Yeongtong-gu, Suwon Gyeonggi-do KR 16681 in the IEEE OUI registry entry for 34:97:6F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
