Which company owns MAC address prefix EC:7C:BA?

MAC address prefix EC:7C:BA is registered to Hewlett Packard Enterprise in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:7C:BA has a network interface built by Hewlett Packard Enterprise.

What is the OUI EC:7C:BA?

EC:7C:BA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Hewlett Packard Enterprise. It covers every address from EC:7C:BA:00:00:00 to EC:7C:BA:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-7C-BA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:7C:BA:00:00:00 that is EC:7C:BA — 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 Hewlett Packard Enterprise located?

Hewlett Packard Enterprise is listed at 1701 E Mossy Oaks Rd Spring TX US 77389 in the IEEE OUI registry entry for EC:7C:BA. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Hewlett Packard Enterprise own?

Hewlett Packard Enterprise holds 176 OUI prefixes in the IEEE registry, of which EC:7C:BA is one. A device made by Hewlett Packard Enterprise could carry a MAC address from any of them.
