FAQ
- Which company owns MAC address prefix D0:63:4D?
- MAC address prefix D0:63:4D is registered to Meiko Maschinenbau GmbH & Co. KG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D0:63:4D has a network interface built by Meiko Maschinenbau GmbH & Co. KG.
- What is the OUI D0:63:4D?
- D0:63:4D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Meiko Maschinenbau GmbH & Co. KG. It covers every address from D0:63:4D:00:00:00 to D0:63:4D:FF:FF:FF, or 16,777,216 addresses in total. It is also written D0-63-4D.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in D0:63:4D:00:00:00 that is D0:63:4D — 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 Meiko Maschinenbau GmbH & Co. KG located?
- Meiko Maschinenbau GmbH & Co. KG is listed at Englerstraße 3 Offenburg DE 77652 in the IEEE OUI registry entry for D0:63:4D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
