Which company owns MAC address prefix EC:F2:36?

MAC address prefix EC:F2:36 is registered to NEOMONTANA ELECTRONICS in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:F2:36 has a network interface built by NEOMONTANA ELECTRONICS.

What is the OUI EC:F2:36?

EC:F2:36 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NEOMONTANA ELECTRONICS. It covers every address from EC:F2:36:00:00:00 to EC:F2:36:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-F2-36.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:F2:36:00:00:00 that is EC:F2:36 — 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 NEOMONTANA ELECTRONICS located?

NEOMONTANA ELECTRONICS is listed at Mladost-4, bl. 483, mag. 13 Sofia BG 1715 in the IEEE OUI registry entry for EC:F2:36. This is the address the organization registered with the IEEE, which may differ from its current operating address.
