Which company owns MAC address prefix 30:D6:59?

MAC address prefix 30:D6:59 is registered to Merging Technologies SA in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 30:D6:59 has a network interface built by Merging Technologies SA.

What is the OUI 30:D6:59?

30:D6:59 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Merging Technologies SA. It covers every address from 30:D6:59:00:00:00 to 30:D6:59:FF:FF:FF, or 16,777,216 addresses in total. It is also written 30-D6-59.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 30:D6:59:00:00:00 that is 30:D6:59 — 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 Merging Technologies SA located?

Merging Technologies SA is listed at Le Verney 4 Puidoux Outside the U.S or Canada CH 1070 in the IEEE OUI registry entry for 30:D6:59. This is the address the organization registered with the IEEE, which may differ from its current operating address.
