Which company owns MAC address prefix 20:D9:06?

MAC address prefix 20:D9:06 is registered to Iota, Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 20:D9:06 has a network interface built by Iota, Inc..

What is the OUI 20:D9:06?

20:D9:06 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Iota, Inc.. It covers every address from 20:D9:06:00:00:00 to 20:D9:06:FF:FF:FF, or 16,777,216 addresses in total. It is also written 20-D9-06.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 20:D9:06:00:00:00 that is 20:D9:06 — 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 Iota, Inc. located?

Iota, Inc. is listed at 2212 Queen Anne Ave. N., #348 Seattle WA US 98109 in the IEEE OUI registry entry for 20:D9:06. This is the address the organization registered with the IEEE, which may differ from its current operating address.
