Which company owns MAC address prefix 68:52:10?

MAC address prefix 68:52:10 is registered to MCS Logic in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:52:10 has a network interface built by MCS Logic.

What is the OUI 68:52:10?

68:52:10 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MCS Logic. It covers every address from 68:52:10:00:00:00 to 68:52:10:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-52-10.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:52:10:00:00:00 that is 68:52:10 — 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 MCS Logic located?

MCS Logic is listed at 128, Beobwon-ro, Songpa-gu, Seoul 05854 seoul KR 05854 in the IEEE OUI registry entry for 68:52:10. This is the address the organization registered with the IEEE, which may differ from its current operating address.

MCS Logic

MAC address prefix 68:52:10 is registered to MCS Logic in the IEEE OUI registry. Any device whose MAC address begins with 68:52:10 has a network interface built by MCS Logic. This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from 68:52:10:00:00:00 to 68:52:10:FF:FF:FF.
