Which company owns MAC address prefix 90:A1:BA?

MAC address prefix 90:A1:BA is registered to PNetworks Electronics Information in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 90:A1:BA has a network interface built by PNetworks Electronics Information.

What is the OUI 90:A1:BA?

90:A1:BA is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to PNetworks Electronics Information. It covers every address from 90:A1:BA:00:00:00 to 90:A1:BA:FF:FF:FF, or 16,777,216 addresses in total. It is also written 90-A1-BA.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 90:A1:BA:00:00:00 that is 90:A1:BA — 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 PNetworks Electronics Information located?

PNetworks Electronics Information is listed at SANAYI MAH. TEKNOPARK BUL. TEKNOPARK A1 BLOK NO: 1-1A IC KAPI NO: 207 PENDIK -ISTANBUL - TURKEY Istanbul Pendik TR 34906 in the IEEE OUI registry entry for 90:A1:BA. This is the address the organization registered with the IEEE, which may differ from its current operating address.
