Which company owns MAC address prefix 70:1A:ED?

MAC address prefix 70:1A:ED is registered to ADVAS CO., LTD. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 70:1A:ED has a network interface built by ADVAS CO., LTD..

What is the OUI 70:1A:ED?

70:1A:ED is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ADVAS CO., LTD.. It covers every address from 70:1A:ED:00:00:00 to 70:1A:ED:FF:FF:FF, or 16,777,216 addresses in total. It is also written 70-1A-ED.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 70:1A:ED:00:00:00 that is 70:1A:ED — 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 ADVAS CO., LTD. located?
