Which company owns MAC address prefix 68:7C:D5?

MAC address prefix 68:7C:D5 is registered to Y Soft Corporation, a.s. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:7C:D5 has a network interface built by Y Soft Corporation, a.s..

What is the OUI 68:7C:D5?

68:7C:D5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Y Soft Corporation, a.s.. It covers every address from 68:7C:D5:00:00:00 to 68:7C:D5:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-7C-D5.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 68:7C:D5:00:00:00 that is 68:7C:D5 — 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 Y Soft Corporation, a.s. located?

Y Soft Corporation, a.s. is listed at Technicka 2948/13 Brno Czech Republic CZ 616 00 in the IEEE OUI registry entry for 68:7C:D5. This is the address the organization registered with the IEEE, which may differ from its current operating address.
