Which company owns MAC address prefix C8:35:B8?

MAC address prefix C8:35:B8 is registered to Ericsson, EAB/RWI/K in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C8:35:B8 has a network interface built by Ericsson, EAB/RWI/K.

What is the OUI C8:35:B8?

C8:35:B8 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ericsson, EAB/RWI/K. It covers every address from C8:35:B8:00:00:00 to C8:35:B8:FF:FF:FF, or 16,777,216 addresses in total. It is also written C8-35-B8.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C8:35:B8:00:00:00 that is C8:35:B8 — 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 Ericsson, EAB/RWI/K located?

Ericsson, EAB/RWI/K is listed at Skolgången 17 SE SE-800 06 in the IEEE OUI registry entry for C8:35:B8. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Ericsson, EAB/RWI/K own?

Ericsson, EAB/RWI/K holds 2 OUI prefixes in the IEEE registry, of which C8:35:B8 is one. A device made by Ericsson, EAB/RWI/K could carry a MAC address from any of them.
