Which company owns MAC address prefix 90:83:7A?

MAC address prefix 90:83:7A is registered to General Electric Water & Process Technologies in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 90:83:7A has a network interface built by General Electric Water & Process Technologies.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 90:83:7A:00:00:00 that is 90:83:7A — 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 General Electric Water & Process Technologies located?

General Electric Water & Process Technologies is listed at 6060 Spine Road Boulder Colorado US 80301-3687 in the IEEE OUI registry entry for 90:83:7A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
