Which company owns MAC address prefix 34:BA:9A?

MAC address prefix 34:BA:9A is registered to Asiatelco Technologies Co. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 34:BA:9A has a network interface built by Asiatelco Technologies Co..

What is the OUI 34:BA:9A?

34:BA:9A is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Asiatelco Technologies Co.. It covers every address from 34:BA:9A:00:00:00 to 34:BA:9A:FF:FF:FF, or 16,777,216 addresses in total. It is also written 34-BA-9A.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 34:BA:9A:00:00:00 that is 34:BA:9A — 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 Asiatelco Technologies Co. located?

Asiatelco Technologies Co. is listed at 301,#8 Building,#289 Bisheng Road Shanghai CN 201204 in the IEEE OUI registry entry for 34:BA:9A. This is the address the organization registered with the IEEE, which may differ from its current operating address.
