Which company owns MAC address prefix 18:6D:99?

MAC address prefix 18:6D:99 is registered to Adanis Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 18:6D:99 has a network interface built by Adanis Inc..

What is the OUI 18:6D:99?

18:6D:99 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Adanis Inc.. It covers every address from 18:6D:99:00:00:00 to 18:6D:99:FF:FF:FF, or 16,777,216 addresses in total. It is also written 18-6D-99.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 18:6D:99:00:00:00 that is 18:6D:99 — 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 Adanis Inc. located?

Adanis Inc. is listed at #2015-2016 Geumkang Penterium Hakuro, Dongan-Gu, Anyang-Si Kyunggi-Do KR 431-060 in the IEEE OUI registry entry for 18:6D:99. This is the address the organization registered with the IEEE, which may differ from its current operating address.
