Which company owns MAC address prefix 00:1F:64?

MAC address prefix 00:1F:64 is registered to Beijing Autelan Technology Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:1F:64 has a network interface built by Beijing Autelan Technology Inc..

What is the OUI 00:1F:64?

00:1F:64 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Beijing Autelan Technology Inc.. It covers every address from 00:1F:64:00:00:00 to 00:1F:64:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-1F-64.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:1F:64:00:00:00 that is 00:1F:64 — 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 Beijing Autelan Technology Inc. located?

Beijing Autelan Technology Inc. is listed at Room B-12B01, Keshi Plaza, Xinxi road, Beijing CN 100085 in the IEEE OUI registry entry for 00:1F:64. This is the address the organization registered with the IEEE, which may differ from its current operating address.
