Which company owns MAC address prefix 30:04:75?

MAC address prefix 30:04:75 is registered to QBIC COMMUNICATIONS DMCC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 30:04:75 has a network interface built by QBIC COMMUNICATIONS DMCC.

What is the OUI 30:04:75?

30:04:75 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to QBIC COMMUNICATIONS DMCC. It covers every address from 30:04:75:00:00:00 to 30:04:75:FF:FF:FF, or 16,777,216 addresses in total. It is also written 30-04-75.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 30:04:75:00:00:00 that is 30:04:75 — 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 QBIC COMMUNICATIONS DMCC located?

QBIC COMMUNICATIONS DMCC is listed at 1003 Palladium Tower JLT Dubai, UAE Dubai AE 393518 in the IEEE OUI registry entry for 30:04:75. This is the address the organization registered with the IEEE, which may differ from its current operating address.
