Which company owns MAC address prefix B4:6A:D4?

MAC address prefix B4:6A:D4 is registered to Edgecore Americas Networking Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with B4:6A:D4 has a network interface built by Edgecore Americas Networking Corporation.

What is the OUI B4:6A:D4?

B4:6A:D4 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Edgecore Americas Networking Corporation. It covers every address from B4:6A:D4:00:00:00 to B4:6A:D4:FF:FF:FF, or 16,777,216 addresses in total. It is also written B4-6A-D4.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in B4:6A:D4:00:00:00 that is B4:6A:D4 — 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 Edgecore Americas Networking Corporation located?

Edgecore Americas Networking Corporation is listed at 20 Mason Irvine US 92618 in the IEEE OUI registry entry for B4:6A:D4. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Edgecore Americas Networking Corporation own?

Edgecore Americas Networking Corporation holds 13 OUI prefixes in the IEEE registry, of which B4:6A:D4 is one. A device made by Edgecore Americas Networking Corporation could carry a MAC address from any of them.
