Which company owns MAC address prefix D4:1A:C8?

MAC address prefix D4:1A:C8 is registered to Nippon Printer Engineering in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D4:1A:C8 has a network interface built by Nippon Printer Engineering.

What is the OUI D4:1A:C8?

D4:1A:C8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Nippon Printer Engineering. It covers every address from D4:1A:C8:00:00:00 to D4:1A:C8:FF:FF:FF, or 16,777,216 addresses in total. It is also written D4-1A-C8.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in D4:1A:C8:00:00:00 that is D4:1A:C8 — 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 Nippon Printer Engineering located?

Nippon Printer Engineering is listed at 2660 Katsuyama Fujikawaguchiko-town Yamanashi-Pref. JP 401-0310 in the IEEE OUI registry entry for D4:1A:C8. This is the address the organization registered with the IEEE, which may differ from its current operating address.
