Which company owns MAC address prefix 50:C0:06?

MAC address prefix 50:C0:06 is registered to Carmanah Signs in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 50:C0:06 has a network interface built by Carmanah Signs.

What is the OUI 50:C0:06?

50:C0:06 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Carmanah Signs. It covers every address from 50:C0:06:00:00:00 to 50:C0:06:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-C0-06.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:C0:06:00:00:00 that is 50:C0:06 — 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 Carmanah Signs located?

Carmanah Signs is listed at #5 6025 12 Street SE Calgary Alberta CA T2H2K1 in the IEEE OUI registry entry for 50:C0:06. This is the address the organization registered with the IEEE, which may differ from its current operating address.
