Which company owns MAC address prefix 54:0B:B6?

MAC address prefix 54:0B:B6 is registered to Variscite LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 54:0B:B6 has a network interface built by Variscite LTD.

What is the OUI 54:0B:B6?

54:0B:B6 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Variscite LTD. It covers every address from 54:0B:B6:00:00:00 to 54:0B:B6:FF:FF:FF, or 16,777,216 addresses in total. It is also written 54-0B-B6.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 54:0B:B6:00:00:00 that is 54:0B:B6 — 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 Variscite LTD located?

Variscite LTD is listed at 15 Ismargad St Kiryat Gat IL 8202041 in the IEEE OUI registry entry for 54:0B:B6. This is the address the organization registered with the IEEE, which may differ from its current operating address.
