Which company owns MAC address prefix 5C:64:0F?

MAC address prefix 5C:64:0F is registered to Sage Technologies Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 5C:64:0F has a network interface built by Sage Technologies Inc..

What is the OUI 5C:64:0F?

5C:64:0F is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Sage Technologies Inc.. It covers every address from 5C:64:0F:00:00:00 to 5C:64:0F:FF:FF:FF, or 16,777,216 addresses in total. It is also written 5C-64-0F.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 5C:64:0F:00:00:00 that is 5C:64:0F — 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 Sage Technologies Inc. located?

Sage Technologies Inc. is listed at Room L308-02, #238, Donglan Road, Minhang Dist. Shanghai Shanghai CN 201102 in the IEEE OUI registry entry for 5C:64:0F. This is the address the organization registered with the IEEE, which may differ from its current operating address.
