Which company owns MAC address prefix 00:50:0E?

MAC address prefix 00:50:0E is registered to CHROMATIS NETWORKS, INC. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:50:0E has a network interface built by CHROMATIS NETWORKS, INC..

What is the OUI 00:50:0E?

00:50:0E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to CHROMATIS NETWORKS, INC.. It covers every address from 00:50:0E:00:00:00 to 00:50:0E:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-50-0E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:50:0E:00:00:00 that is 00:50:0E — 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 CHROMATIS NETWORKS, INC. located?

CHROMATIS NETWORKS, INC. is listed at 3 BETHESDA METRO CENTER BETHESDA MD US 20814 in the IEEE OUI registry entry for 00:50:0E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
