Which company owns MAC address prefix 24:DC:0F?

MAC address prefix 24:DC:0F is registered to Phytium Technology Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 24:DC:0F has a network interface built by Phytium Technology Co.,Ltd..

What is the OUI 24:DC:0F?

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

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 24:DC:0F:00:00:00 that is 24:DC:0F — 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 Phytium Technology Co.,Ltd. located?

Phytium Technology Co.,Ltd. is listed at Building5,XinAn Business Square,Haiyuan Middle Road Binhai New District, Tianjin CN 300450 in the IEEE OUI registry entry for 24:DC:0F. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Phytium Technology Co.,Ltd. own?

Phytium Technology Co.,Ltd. holds 4 OUI prefixes in the IEEE registry, of which 24:DC:0F is one. A device made by Phytium Technology Co.,Ltd. could carry a MAC address from any of them.
