FAQ
- Which company owns MAC address prefix D8:EF:CD?
- MAC address prefix D8:EF:CD is registered to Nokia Solutions and Networks GmbH & Co. KG in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with D8:EF:CD has a network interface built by Nokia Solutions and Networks GmbH & Co. KG.
- What is the OUI D8:EF:CD?
- D8:EF:CD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Nokia Solutions and Networks GmbH & Co. KG. It covers every address from D8:EF:CD:00:00:00 to D8:EF:CD:FF:FF:FF, or 16,777,216 addresses in total. It is also written D8-EF-CD.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in D8:EF:CD:00:00:00 that is D8:EF:CD — 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 Nokia Solutions and Networks GmbH & Co. KG located?
- Nokia Solutions and Networks GmbH & Co. KG is listed at Werinherstrasse 91 München Bavaria DE D-81541 in the IEEE OUI registry entry for D8:EF:CD. This is the address the organization registered with the IEEE, which may differ from its current operating address.
- How many MAC prefixes does Nokia Solutions and Networks GmbH & Co. KG own?
- Nokia Solutions and Networks GmbH & Co. KG holds 35 OUI prefixes in the IEEE registry, of which D8:EF:CD is one. A device made by Nokia Solutions and Networks GmbH & Co. KG could carry a MAC address from any of them.
