Which company owns MAC address prefix 58:D5:0A?

MAC address prefix 58:D5:0A is registered to Murata Manufacturing Co., Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 58:D5:0A has a network interface built by Murata Manufacturing Co., Ltd..

What is the OUI 58:D5:0A?

58:D5:0A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Murata Manufacturing Co., Ltd.. It covers every address from 58:D5:0A:00:00:00 to 58:D5:0A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 58-D5-0A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 58:D5:0A:00:00:00 that is 58:D5:0A — 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 Murata Manufacturing Co., Ltd. located?
