What is the OUI 74:34:00?

74:34:00 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MTG Co., Ltd.. It covers every address from 74:34:00:00:00:00 to 74:34:00:FF:FF:FF, or 16,777,216 addresses in total. It is also written 74-34-00.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 74:34:00:00:00:00 that is 74:34:00 — 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 MTG Co., Ltd. located?

MTG Co., Ltd. is listed at MTG No. 2 HIKARI Bldg., 4-13 Honjindori Nakamura-ku, Nagoya Aichi JP 453-0041 in the IEEE OUI registry entry for 74:34:00. This is the address the organization registered with the IEEE, which may differ from its current operating address.
