Which company owns MAC address prefix 78:00:A8?

MAC address prefix 78:00:A8 is registered to PT HAN SUNG ELECTORONICS INDONESIA in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 78:00:A8 has a network interface built by PT HAN SUNG ELECTORONICS INDONESIA.

What is the OUI 78:00:A8?

78:00:A8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to PT HAN SUNG ELECTORONICS INDONESIA. It covers every address from 78:00:A8:00:00:00 to 78:00:A8:FF:FF:FF, or 16,777,216 addresses in total. It is also written 78-00-A8.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 78:00:A8:00:00:00 that is 78:00:A8 — 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 PT HAN SUNG ELECTORONICS INDONESIA located?
