Which company owns MAC address prefix 10:37:11?

MAC address prefix 10:37:11 is registered to NORBIT ITS in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 10:37:11 has a network interface built by NORBIT ITS.

What is the OUI 10:37:11?

10:37:11 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NORBIT ITS. It covers every address from 10:37:11:00:00:00 to 10:37:11:FF:FF:FF, or 16,777,216 addresses in total. It is also written 10-37-11.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 10:37:11:00:00:00 that is 10:37:11 — 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 NORBIT ITS located?

NORBIT ITS is listed at Otto Nielsens Veg 12 Trondheim NO N-7004 in the IEEE OUI registry entry for 10:37:11. This is the address the organization registered with the IEEE, which may differ from its current operating address.

NORBIT ITS

MAC address prefix 10:37:11 is registered to NORBIT ITS in the IEEE OUI registry. Any device whose MAC address begins with 10:37:11 has a network interface built by NORBIT ITS. This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from 10:37:11:00:00:00 to 10:37:11:FF:FF:FF.
