FAQ

Which company owns MAC address prefix 00:77:E4?
MAC address prefix 00:77:E4 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 00:77:E4 has a network interface built by Nokia Solutions and Networks GmbH & Co. KG.
What is the OUI 00:77:E4?
00:77:E4 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 00:77:E4:00:00:00 to 00:77:E4:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-77-E4.
How do I find the manufacturer of a MAC address?
Take the first three octets of the address — in 00:77:E4:00:00:00 that is 00:77:E4 — 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 00:77:E4. This is the address the organization registered with the IEEE, which may differ from its current operating address.
