FAQ
- Which company owns MAC address prefix B8:97:7A?
- MAC address prefix B8:97:7A 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 B8:97:7A has a network interface built by Nokia Solutions and Networks GmbH & Co. KG.
- What is the OUI B8:97:7A?
- B8:97:7A 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 B8:97:7A:00:00:00 to B8:97:7A:FF:FF:FF, or 16,777,216 addresses in total. It is also written B8-97-7A.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in B8:97:7A:00:00:00 that is B8:97:7A — 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?
