Which company owns MAC address prefix 44:6C:24?

MAC address prefix 44:6C:24 is registered to Reallin Electronic Co.,Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 44:6C:24 has a network interface built by Reallin Electronic Co.,Ltd.

What is the OUI 44:6C:24?

44:6C:24 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Reallin Electronic Co.,Ltd. It covers every address from 44:6C:24:00:00:00 to 44:6C:24:FF:FF:FF, or 16,777,216 addresses in total. It is also written 44-6C-24.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 44:6C:24:00:00:00 that is 44:6C:24 — 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 Reallin Electronic Co.,Ltd located?

Reallin Electronic Co.,Ltd is listed at 2/F, Building 3, No.202 Zhengzhong Rd, XiHu industry Park Hang Zhou Zhe Jiang CN 310030 in the IEEE OUI registry entry for 44:6C:24. This is the address the organization registered with the IEEE, which may differ from its current operating address.
