Which company owns MAC address prefix 90:0E:84?

MAC address prefix 90:0E:84 is registered to eero inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 90:0E:84 has a network interface built by eero inc..

What is the OUI 90:0E:84?

90:0E:84 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to eero inc.. It covers every address from 90:0E:84:00:00:00 to 90:0E:84:FF:FF:FF, or 16,777,216 addresses in total. It is also written 90-0E-84.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 90:0E:84:00:00:00 that is 90:0E:84 — 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 eero inc. located?

eero inc. is listed at 660 3rd Street San Francisco CA US 94107 in the IEEE OUI registry entry for 90:0E:84. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does eero inc. own?

eero inc. holds 116 OUI prefixes in the IEEE registry, of which 90:0E:84 is one. A device made by eero inc. could carry a MAC address from any of them.
