Which company owns MAC address prefix 04:70:BC?

MAC address prefix 04:70:BC is registered to Globalstar Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:70:BC has a network interface built by Globalstar Inc..

What is the OUI 04:70:BC?

04:70:BC is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Globalstar Inc.. It covers every address from 04:70:BC:00:00:00 to 04:70:BC:FF:FF:FF, or 16,777,216 addresses in total. It is also written 04-70-BC.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:70:BC:00:00:00 that is 04:70:BC — 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 Globalstar Inc. located?

Globalstar Inc. is listed at 461 S Milpitas Blvd Milpitas CA US 95035 in the IEEE OUI registry entry for 04:70:BC. This is the address the organization registered with the IEEE, which may differ from its current operating address.
