Which company owns MAC address prefix 04:6F:00?

MAC address prefix 04:6F:00 is registered to LG Electronics in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:6F:00 has a network interface built by LG Electronics.

What is the OUI 04:6F:00?

04:6F:00 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to LG Electronics. It covers every address from 04:6F:00:00:00:00 to 04:6F:00:FF:FF:FF, or 16,777,216 addresses in total. It is also written 04-6F-00.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:6F:00:00:00:00 that is 04:6F: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 LG Electronics located?

LG Electronics is listed at Lot CN02, Trang Due Industrial Park,An Phong Ward, Hai Phong City, Vietnam Hai Phong VN 184956 in the IEEE OUI registry entry for 04:6F:00. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does LG Electronics own?

LG Electronics holds 29 OUI prefixes in the IEEE registry, of which 04:6F:00 is one. A device made by LG Electronics could carry a MAC address from any of them.
