Which company owns MAC address prefix D8:29:16?

MAC address prefix D8:29:16 is registered to Ascent Communication Technology in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:29:16 has a network interface built by Ascent Communication Technology.

What is the OUI D8:29:16?

D8:29:16 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ascent Communication Technology. It covers every address from D8:29:16:00:00:00 to D8:29:16:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-29-16.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D8:29:16:00:00:00 that is D8:29:16 — 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 Ascent Communication Technology located?

Ascent Communication Technology is listed at 13/F., Shum Tower Hong Kong HK 9999 in the IEEE OUI registry entry for D8:29:16. This is the address the organization registered with the IEEE, which may differ from its current operating address.
