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

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

What is the OUI 70:7E:DE?

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

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 70:7E:DE:00:00:00 that is 70:7E:DE — 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 NASTEC LTD. located?

NASTEC LTD. is listed at 111-D, Krasnorechenskaya str. Khabarovsk RU 680006 in the IEEE OUI registry entry for 70:7E:DE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
