Which company owns MAC address prefix 20:0F:70?

MAC address prefix 20:0F:70 is registered to FOXTECH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 20:0F:70 has a network interface built by FOXTECH.

What is the OUI 20:0F:70?

20:0F:70 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to FOXTECH. It covers every address from 20:0F:70:00:00:00 to 20:0F:70:FF:FF:FF, or 16,777,216 addresses in total. It is also written 20-0F-70.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 20:0F:70:00:00:00 that is 20:0F:70 — 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 FOXTECH located?

FOXTECH is listed at 152-160 City Road LONDON KEMP HOUSE GB EC1V 2NX in the IEEE OUI registry entry for 20:0F:70. This is the address the organization registered with the IEEE, which may differ from its current operating address.
