Which company owns MAC address prefix 78:6D:EB?

MAC address prefix 78:6D:EB is registered to GE Lighting in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 78:6D:EB has a network interface built by GE Lighting.

What is the OUI 78:6D:EB?

78:6D:EB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to GE Lighting. It covers every address from 78:6D:EB:00:00:00 to 78:6D:EB:FF:FF:FF, or 16,777,216 addresses in total. It is also written 78-6D-EB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 78:6D:EB:00:00:00 that is 78:6D:EB — 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 GE Lighting located?

GE Lighting is listed at 1975 Noble Rd East Cleveland OH US 44112 in the IEEE OUI registry entry for 78:6D:EB. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does GE Lighting own?

GE Lighting holds 3 OUI prefixes in the IEEE registry, of which 78:6D:EB is one. A device made by GE Lighting could carry a MAC address from any of them.
