Which company owns MAC address prefix EC:01:E2?

MAC address prefix EC:01:E2 is registered to FOXCONN INTERCONNECT TECHNOLOGY in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with EC:01:E2 has a network interface built by FOXCONN INTERCONNECT TECHNOLOGY.

What is the OUI EC:01:E2?

EC:01:E2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to FOXCONN INTERCONNECT TECHNOLOGY. It covers every address from EC:01:E2:00:00:00 to EC:01:E2:FF:FF:FF, or 16,777,216 addresses in total. It is also written EC-01-E2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in EC:01:E2:00:00:00 that is EC:01:E2 — 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 FOXCONN INTERCONNECT TECHNOLOGY located?

FOXCONN INTERCONNECT TECHNOLOGY is listed at 66-1, Chungshan Rd., Tucheng Dist. New Taipei City Taiwan (R.O.C.) TW 23680 in the IEEE OUI registry entry for EC:01:E2. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does FOXCONN INTERCONNECT TECHNOLOGY own?

FOXCONN INTERCONNECT TECHNOLOGY holds 2 OUI prefixes in the IEEE registry, of which EC:01:E2 is one. A device made by FOXCONN INTERCONNECT TECHNOLOGY could carry a MAC address from any of them.
