Which company owns MAC address prefix 24:40:AE?

MAC address prefix 24:40:AE is registered to NIIC Technology Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 24:40:AE has a network interface built by NIIC Technology Co., Ltd..

What is the OUI 24:40:AE?

24:40:AE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NIIC Technology Co., Ltd.. It covers every address from 24:40:AE:00:00:00 to 24:40:AE:FF:FF:FF, or 16,777,216 addresses in total. It is also written 24-40-AE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 24:40:AE:00:00:00 that is 24:40:AE — 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 NIIC Technology Co., Ltd. located?

NIIC Technology Co., Ltd. is listed at Room 8218, Building 3#B, No. 268 Furong Road, Jingkai District Hefei CN 230601 in the IEEE OUI registry entry for 24:40:AE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
