What is the OUI 4C:DC:0D?

4C:DC:0D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Coral Telecom Limited. It covers every address from 4C:DC:0D:00:00:00 to 4C:DC:0D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 4C-DC-0D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 4C:DC:0D:00:00:00 that is 4C:DC:0D — 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.

Coral Telecom Limited is listed at E-2, Sector 63 Noida Uttar Pradesh IN 201301 in the IEEE OUI registry entry for 4C:DC:0D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
