Which company owns MAC address prefix 60:D7:E3?

MAC address prefix 60:D7:E3 is registered to IEEE Registration Authority in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 60:D7:E3 has a network interface built by IEEE Registration Authority.

What is the OUI 60:D7:E3?

60:D7:E3 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to IEEE Registration Authority. It covers every address from 60:D7:E3:00:00:00 to 60:D7:E3:FF:FF:FF, or 16,777,216 addresses in total. It is also written 60-D7-E3.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 60:D7:E3:00:00:00 that is 60:D7:E3 — 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 IEEE Registration Authority located?

IEEE Registration Authority is listed at 445 Hoes Lane Piscataway NJ US 08554 in the IEEE OUI registry entry for 60:D7:E3. This is the address the organization registered with the IEEE, which may differ from its current operating address.

IEEE Registration Authority

MAC address prefix 60:D7:E3 is registered to IEEE Registration Authority in the IEEE OUI registry. Any device whose MAC address begins with 60:D7:E3 has a network interface built by IEEE Registration Authority. This prefix (the OUI, or Organizationally Unique Identifier) is assigned by the IEEE and is the first three octets of the address — it covers every MAC from 60:D7:E3:00:00:00 to 60:D7:E3:FF:FF:FF.
