Which company owns MAC address prefix 88:97:65?

MAC address prefix 88:97:65 is registered to exands in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 88:97:65 has a network interface built by exands.

What is the OUI 88:97:65?

88:97:65 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to exands. It covers every address from 88:97:65:00:00:00 to 88:97:65:FF:FF:FF, or 16,777,216 addresses in total. It is also written 88-97-65.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 88:97:65:00:00:00 that is 88:97:65 — 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 exands located?

exands is listed at RM2202 , No. 666 Gubei road shanghai CN 200336 in the IEEE OUI registry entry for 88:97:65. This is the address the organization registered with the IEEE, which may differ from its current operating address.
