Which company owns MAC address prefix 00:24:EC?

MAC address prefix 00:24:EC is registered to United Information Technology Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:24:EC has a network interface built by United Information Technology Co.,Ltd..

What is the OUI 00:24:EC?

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

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:24:EC:00:00:00 that is 00:24:EC — 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 United Information Technology Co.,Ltd. located?

United Information Technology Co.,Ltd. is listed at 5/F,9th Building,Software Park,2nd Keji-zhong Road,High-Tech Industrial Park Shenzhen Guangdong CN 518057 in the IEEE OUI registry entry for 00:24:EC.
