Which company owns MAC address prefix 50:67:E0?

MAC address prefix 50:67:E0 is registered to Altice Labs in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 50:67:E0 has a network interface built by Altice Labs.

What is the OUI 50:67:E0?

50:67:E0 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Altice Labs. It covers every address from 50:67:E0:00:00:00 to 50:67:E0:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-67-E0.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:67:E0:00:00:00 that is 50:67:E0 — 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 Altice Labs located?

Altice Labs is listed at Rua Engenheiro José Ferreira Pinto Basto, VAT PT504705610 Aveiro Aveiro PT 3810-106 in the IEEE OUI registry entry for 50:67:E0. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Altice Labs own?

Altice Labs holds 5 OUI prefixes in the IEEE registry, of which 50:67:E0 is one. A device made by Altice Labs could carry a MAC address from any of them.
