Which company owns MAC address prefix 88:95:B9?

MAC address prefix 88:95:B9 is registered to Unified Packet Systems Crop in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 88:95:B9 has a network interface built by Unified Packet Systems Crop.

What is the OUI 88:95:B9?

88:95:B9 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Unified Packet Systems Crop. It covers every address from 88:95:B9:00:00:00 to 88:95:B9:FF:FF:FF, or 16,777,216 addresses in total. It is also written 88-95-B9.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 88:95:B9:00:00:00 that is 88:95:B9 — 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 Unified Packet Systems Crop located?

Unified Packet Systems Crop is listed at 1F., No32,Lane 15,SEC 6, MinQuan E Rd., Taipei Neihu TW 114 in the IEEE OUI registry entry for 88:95:B9. This is the address the organization registered with the IEEE, which may differ from its current operating address.
