Which company owns MAC address prefix 00:60:DB?

MAC address prefix 00:60:DB is registered to NTP ELEKTRONIK A/S in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:60:DB has a network interface built by NTP ELEKTRONIK A/S.

What is the OUI 00:60:DB?

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

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:60:DB:00:00:00 that is 00:60:DB — 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 NTP ELEKTRONIK A/S located?

NTP ELEKTRONIK A/S is listed at KNAPHOLM 7 DK-2730 HERLEV DK in the IEEE OUI registry entry for 00:60:DB. This is the address the organization registered with the IEEE, which may differ from its current operating address.

NTP ELEKTRONIK A/S

MAC address prefix 00:60:DB is registered to NTP ELEKTRONIK A/S in the IEEE OUI registry. Any device whose MAC address begins with 00:60:DB has a network interface built by NTP ELEKTRONIK A/S. 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 00:60:DB:00:00:00 to 00:60:DB:FF:FF:FF.
