Which company owns MAC address prefix 90:F7:B2?

MAC address prefix 90:F7:B2 is registered to New H3C Technologies Co., Ltd in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 90:F7:B2 has a network interface built by New H3C Technologies Co., Ltd.

What is the OUI 90:F7:B2?

90:F7:B2 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to New H3C Technologies Co., Ltd. It covers every address from 90:F7:B2:00:00:00 to 90:F7:B2:FF:FF:FF, or 16,777,216 addresses in total. It is also written 90-F7-B2.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 90:F7:B2:00:00:00 that is 90:F7:B2 — 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 New H3C Technologies Co., Ltd located?

New H3C Technologies Co., Ltd is listed at 466 Changhe Road, Binjiang District Hangzhou Zhejiang CN 310052 in the IEEE OUI registry entry for 90:F7:B2. This is the address the organization registered with the IEEE, which may differ from its current operating address.
