Which company owns MAC address prefix B4:79:47?

MAC address prefix B4:79:47 is registered to Nutanix in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B4:79:47 has a network interface built by Nutanix.

What is the OUI B4:79:47?

B4:79:47 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Nutanix. It covers every address from B4:79:47:00:00:00 to B4:79:47:FF:FF:FF, or 16,777,216 addresses in total. It is also written B4-79-47.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B4:79:47:00:00:00 that is B4:79:47 — 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 Nutanix located?

Nutanix is listed at 1740 Technology Drive Ste #150 San Jose CA US 95110 in the IEEE OUI registry entry for B4:79:47. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Nutanix own?

Nutanix holds 3 OUI prefixes in the IEEE registry, of which B4:79:47 is one. A device made by Nutanix could carry a MAC address from any of them.
