Which company owns MAC address prefix B4:0E:DC?

MAC address prefix B4:0E:DC is registered to LG-Ericsson Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B4:0E:DC has a network interface built by LG-Ericsson Co.,Ltd..

What is the OUI B4:0E:DC?

B4:0E:DC is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to LG-Ericsson Co.,Ltd.. It covers every address from B4:0E:DC:00:00:00 to B4:0E:DC:FF:FF:FF, or 16,777,216 addresses in total. It is also written B4-0E-DC.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B4:0E:DC:00:00:00 that is B4:0E:DC — 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-Ericsson Co.,Ltd. located?

LG-Ericsson Co.,Ltd. is listed at 533,Hogye-1dong,Dongan-gu Anyang-shi Kyungki-do KR 431-749 in the IEEE OUI registry entry for B4:0E:DC. This is the address the organization registered with the IEEE, which may differ from its current operating address.
