Which company owns MAC address prefix 70:D5:7E?

MAC address prefix 70:D5:7E is registered to Scalar Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 70:D5:7E has a network interface built by Scalar Corporation.

What is the OUI 70:D5:7E?

70:D5:7E is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Scalar Corporation. It covers every address from 70:D5:7E:00:00:00 to 70:D5:7E:FF:FF:FF, or 16,777,216 addresses in total. It is also written 70-D5-7E.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 70:D5:7E:00:00:00 that is 70:D5:7E — 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 Scalar Corporation located?

Scalar Corporation is listed at 1F San-Ei Bldg Shinjuku-ku Tokyo JP 160-0023 in the IEEE OUI registry entry for 70:D5:7E. This is the address the organization registered with the IEEE, which may differ from its current operating address.
