Which company owns MAC address prefix A8:F7:E0?

MAC address prefix A8:F7:E0 is registered to PLANET Technology Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with A8:F7:E0 has a network interface built by PLANET Technology Corporation.

What is the OUI A8:F7:E0?

A8:F7:E0 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to PLANET Technology Corporation. It covers every address from A8:F7:E0:00:00:00 to A8:F7:E0:FF:FF:FF, or 16,777,216 addresses in total. It is also written A8-F7-E0.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in A8:F7:E0:00:00:00 that is A8:F7:E0 — 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 PLANET Technology Corporation located?

PLANET Technology Corporation is listed at 11F, No. 96, Min Quan Road, New Taipei City TW 22341 in the IEEE OUI registry entry for A8:F7:E0. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does PLANET Technology Corporation own?

PLANET Technology Corporation holds 3 OUI prefixes in the IEEE registry, of which A8:F7:E0 is one. A device made by PLANET Technology Corporation could carry a MAC address from any of them.
