Which company owns MAC address prefix 64:8F:DB?

MAC address prefix 64:8F:DB is registered to Huaqin Technology Co.LTD in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 64:8F:DB has a network interface built by Huaqin Technology Co.LTD.

What is the OUI 64:8F:DB?

64:8F:DB is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Huaqin Technology Co.LTD. It covers every address from 64:8F:DB:00:00:00 to 64:8F:DB:FF:FF:FF, or 16,777,216 addresses in total. It is also written 64-8F-DB.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 64:8F:DB:00:00:00 that is 64:8F:DB — 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 Huaqin Technology Co.LTD located?

Huaqin Technology Co.LTD is listed at 11th Floor,Unit 12,No.399 Keyuan Road,Pudong, Shanghai Shanghai Pudong CN 201203 in the IEEE OUI registry entry for 64:8F:DB. This is the address the organization registered with the IEEE, which may differ from its current operating address.
