What is the OUI A8:26:D9?

A8:26:D9 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to HTC Corporation. It covers every address from A8:26:D9:00:00:00 to A8:26:D9:FF:FF:FF, or 16,777,216 addresses in total. It is also written A8-26-D9.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A8:26:D9:00:00:00 that is A8:26:D9 — 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.
