Which company owns MAC address prefix 74:29:20?

MAC address prefix 74:29:20 is registered to MCX-PRO Kft. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 74:29:20 has a network interface built by MCX-PRO Kft..

What is the OUI 74:29:20?

74:29:20 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MCX-PRO Kft.. It covers every address from 74:29:20:00:00:00 to 74:29:20:FF:FF:FF, or 16,777,216 addresses in total. It is also written 74-29-20.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 74:29:20:00:00:00 that is 74:29:20 — 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 MCX-PRO Kft. located?

MCX-PRO Kft. is listed at Etele tér 4. 3.em. Budapest HU 1115 in the IEEE OUI registry entry for 74:29:20. This is the address the organization registered with the IEEE, which may differ from its current operating address.
