Which company owns MAC address prefix 6C:71:BD?

MAC address prefix 6C:71:BD is registered to EZELINK TELECOM in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 6C:71:BD has a network interface built by EZELINK TELECOM.

What is the OUI 6C:71:BD?

6C:71:BD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to EZELINK TELECOM. It covers every address from 6C:71:BD:00:00:00 to 6C:71:BD:FF:FF:FF, or 16,777,216 addresses in total. It is also written 6C-71-BD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 6C:71:BD:00:00:00 that is 6C:71:BD — 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 EZELINK TELECOM located?

EZELINK TELECOM is listed at Bay Square Building 06 - Office No 105 Dubai Dubai AE 111581 in the IEEE OUI registry entry for 6C:71:BD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
