Which company owns MAC address prefix 00:14:57?

MAC address prefix 00:14:57 is registered to Nevion in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:14:57 has a network interface built by Nevion.

What is the OUI 00:14:57?

00:14:57 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Nevion. It covers every address from 00:14:57:00:00:00 to 00:14:57:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-14-57.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:14:57:00:00:00 that is 00:14:57 — 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 Nevion located?

Nevion is listed at Lysaker Torg 5 Lysaker NO NO-1366 in the IEEE OUI registry entry for 00:14:57. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Nevion own?

Nevion holds 3 OUI prefixes in the IEEE registry, of which 00:14:57 is one. A device made by Nevion could carry a MAC address from any of them.
