Which company owns MAC address prefix A8:63:08?

MAC address prefix A8:63:08 is registered to AVUTEC in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A8:63:08 has a network interface built by AVUTEC.

What is the OUI A8:63:08?

A8:63:08 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to AVUTEC. It covers every address from A8:63:08:00:00:00 to A8:63:08:FF:FF:FF, or 16,777,216 addresses in total. It is also written A8-63-08.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A8:63:08:00:00:00 that is A8:63:08 — 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 AVUTEC located?

AVUTEC is listed at Neerloopweg 30 Breda Noord-Brabant NL 4814 RS in the IEEE OUI registry entry for A8:63:08. This is the address the organization registered with the IEEE, which may differ from its current operating address.
