Which company owns MAC address prefix CC:EB:18?

MAC address prefix CC:EB:18 is registered to OOO "TSS" in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with CC:EB:18 has a network interface built by OOO "TSS".

What is the OUI CC:EB:18?

CC:EB:18 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to OOO "TSS". It covers every address from CC:EB:18:00:00:00 to CC:EB:18:FF:FF:FF, or 16,777,216 addresses in total. It is also written CC-EB-18.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in CC:EB:18:00:00:00 that is CC:EB:18 — 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 OOO "TSS" located?

OOO "TSS" is listed at ul. Borisovskaya, 1 Moscow Moscow RU 105187 in the IEEE OUI registry entry for CC:EB:18. This is the address the organization registered with the IEEE, which may differ from its current operating address.

OOO "TSS"
