Which company owns MAC address prefix 90:DA:4E?

MAC address prefix 90:DA:4E is registered to AVANU in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 90:DA:4E has a network interface built by AVANU.

What is the OUI 90:DA:4E?

90:DA:4E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to AVANU. It covers every address from 90:DA:4E:00:00:00 to 90:DA:4E:FF:FF:FF, or 16,777,216 addresses in total. It is also written 90-DA-4E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 90:DA:4E:00:00:00 that is 90:DA:4E — 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 AVANU located?

AVANU is listed at 5205 Prospect Rd San Jose CA US 95129-5034 in the IEEE OUI registry entry for 90:DA:4E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
