Which company owns MAC address prefix 00:16:19?

MAC address prefix 00:16:19 is registered to Lancelan Technologies S.L. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:16:19 has a network interface built by Lancelan Technologies S.L..

What is the OUI 00:16:19?

00:16:19 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Lancelan Technologies S.L.. It covers every address from 00:16:19:00:00:00 to 00:16:19:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-16-19.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:16:19:00:00:00 that is 00:16:19 — 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 Lancelan Technologies S.L. located?

Lancelan Technologies S.L. is listed at C/Angel Guimera 208 bis Terrassa Barcelona ES 08223 in the IEEE OUI registry entry for 00:16:19. This is the address the organization registered with the IEEE, which may differ from its current operating address.
