Which company owns MAC address prefix CC:1E:AB?

MAC address prefix CC:1E:AB is registered to LEDATEL sp. z o.o. i Wspólnicy sp.k in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:1E:AB has a network interface built by LEDATEL sp. z o.o. i Wspólnicy sp.k.

What is the OUI CC:1E:AB?

CC:1E:AB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to LEDATEL sp. z o.o. i Wspólnicy sp.k. It covers every address from CC:1E:AB:00:00:00 to CC:1E:AB:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-1E-AB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:1E:AB:00:00:00 that is CC:1E:AB — 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 LEDATEL sp. z o.o. i Wspólnicy sp.k located?
