Which company owns MAC address prefix 00:11:E1?

MAC address prefix 00:11:E1 is registered to Arcelik A.S in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:11:E1 has a network interface built by Arcelik A.S.

What is the OUI 00:11:E1?

00:11:E1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Arcelik A.S. It covers every address from 00:11:E1:00:00:00 to 00:11:E1:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-11-E1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:11:E1:00:00:00 that is 00:11:E1 — 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 Arcelik A.S located?

Arcelik A.S is listed at Cumhuriyet Mah., E5 Yan Yol, No:1, Istanbul TR 34520 in the IEEE OUI registry entry for 00:11:E1. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Arcelik A.S own?

Arcelik A.S holds 2 OUI prefixes in the IEEE registry, of which 00:11:E1 is one. A device made by Arcelik A.S could carry a MAC address from any of them.
