Which company owns MAC address prefix 04:04:EA?

MAC address prefix 04:04:EA is registered to Valens Semiconductor Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:04:EA has a network interface built by Valens Semiconductor Ltd..

What is the OUI 04:04:EA?

04:04:EA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Valens Semiconductor Ltd.. It covers every address from 04:04:EA:00:00:00 to 04:04:EA:FF:FF:FF, or 16,777,216 addresses in total. It is also written 04-04-EA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:04:EA:00:00:00 that is 04:04:EA — 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 Valens Semiconductor Ltd. located?

Valens Semiconductor Ltd. is listed at 8 Hanagar Street Hod Hasharon Hod Hasharon IL 4501309 in the IEEE OUI registry entry for 04:04:EA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
