Which company owns MAC address prefix 60:15:21?

MAC address prefix 60:15:21 is registered to Redarc Electronics in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 60:15:21 has a network interface built by Redarc Electronics.

What is the OUI 60:15:21?

60:15:21 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Redarc Electronics. It covers every address from 60:15:21:00:00:00 to 60:15:21:FF:FF:FF, or 16,777,216 addresses in total. It is also written 60-15-21.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 60:15:21:00:00:00 that is 60:15:21 — 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 Redarc Electronics located?

Redarc Electronics is listed at 23 Brodie Road (North) Lonsdale South Australia AU 5160 in the IEEE OUI registry entry for 60:15:21. This is the address the organization registered with the IEEE, which may differ from its current operating address.
