Which company owns MAC address prefix 74:4D:79?

MAC address prefix 74:4D:79 is registered to Arrive Systems Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 74:4D:79 has a network interface built by Arrive Systems Inc..

What is the OUI 74:4D:79?

74:4D:79 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Arrive Systems Inc.. It covers every address from 74:4D:79:00:00:00 to 74:4D:79:FF:FF:FF, or 16,777,216 addresses in total. It is also written 74-4D-79.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 74:4D:79:00:00:00 that is 74:4D:79 — 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 Arrive Systems Inc. located?

Arrive Systems Inc. is listed at 1404 Franklin Street, # 350 Oakland CA US 94612 in the IEEE OUI registry entry for 74:4D:79. This is the address the organization registered with the IEEE, which may differ from its current operating address.
