Which company owns MAC address prefix AC:AB:8D?

MAC address prefix AC:AB:8D is registered to Lyngso Marine A/S in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with AC:AB:8D has a network interface built by Lyngso Marine A/S.

What is the OUI AC:AB:8D?

AC:AB:8D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Lyngso Marine A/S. It covers every address from AC:AB:8D:00:00:00 to AC:AB:8D:FF:FF:FF, or 16,777,216 addresses in total. It is also written AC-AB-8D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in AC:AB:8D:00:00:00 that is AC:AB:8D — 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 Lyngso Marine A/S located?

Lyngso Marine A/S is listed at Lyngso Alle 2 Horsholm DK DK-2970 in the IEEE OUI registry entry for AC:AB:8D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
