Which company owns MAC address prefix 00:0F:E4?

MAC address prefix 00:0F:E4 is registered to Pantech Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:0F:E4 has a network interface built by Pantech Co.,Ltd.

What is the OUI 00:0F:E4?

00:0F:E4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Pantech Co.,Ltd. It covers every address from 00:0F:E4:00:00:00 to 00:0F:E4:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-0F-E4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:0F:E4:00:00:00 that is 00:0F:E4 — 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 Pantech Co.,Ltd located?

Pantech Co.,Ltd is listed at Shinsong B/D 3F, 25-12, Youngdeungpo-GU Seoul KR 150-711 in the IEEE OUI registry entry for 00:0F:E4. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Pantech Co.,Ltd own?

Pantech Co.,Ltd holds 2 OUI prefixes in the IEEE registry, of which 00:0F:E4 is one. A device made by Pantech Co.,Ltd could carry a MAC address from any of them.
