Which company owns MAC address prefix 70:0F:EC?

MAC address prefix 70:0F:EC is registered to Poindus Systems Corp. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 70:0F:EC has a network interface built by Poindus Systems Corp..

What is the OUI 70:0F:EC?

70:0F:EC is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Poindus Systems Corp.. It covers every address from 70:0F:EC:00:00:00 to 70:0F:EC:FF:FF:FF, or 16,777,216 addresses in total. It is also written 70-0F-EC.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 70:0F:EC:00:00:00 that is 70:0F:EC — 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 Poindus Systems Corp. located?

Poindus Systems Corp. is listed at 5F., No. 59, Lane. 77, Xing-Ai Rd., Neihu Dist., Taipei City TW 114 in the IEEE OUI registry entry for 70:0F:EC. This is the address the organization registered with the IEEE, which may differ from its current operating address.
