Which company owns MAC address prefix 38:01:97?

MAC address prefix 38:01:97 is registered to TSST Global,Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 38:01:97 has a network interface built by TSST Global,Inc.

What is the OUI 38:01:97?

38:01:97 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to TSST Global,Inc. It covers every address from 38:01:97:00:00:00 to 38:01:97:FF:FF:FF, or 16,777,216 addresses in total. It is also written 38-01-97.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 38:01:97:00:00:00 that is 38:01:97 — 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 TSST Global,Inc located?

TSST Global,Inc is listed at 14 Floor, Bldg. No. 102, Digital Empire2, 486, Sin-dong, Yeongtong-gu, Suwon-si, Su-won Gyeonggi KR 443-734 in the IEEE OUI registry entry for 38:01:97. This is the address the organization registered with the IEEE, which may differ from its current operating address.
