FAQ
- Which company owns MAC address prefix B4:63:6F?
- MAC address prefix B4:63:6F 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 B4:63:6F has a network interface built by Nokia Solutions and Networks GmbH & Co. KG.
- What is the OUI B4:63:6F?
- B4:63:6F 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 B4:63:6F:00:00:00 to B4:63:6F:FF:FF:FF, or 16,777,216 addresses in total. It is also written B4-63-6F.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in B4:63:6F:00:00:00 that is B4:63:6F — 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 B4:63:6F. 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 B4:63:6F is one. A device made by Nokia Solutions and Networks GmbH & Co. KG could carry a MAC address from any of them.
