- What is the OUI 64:CF:13?
- 64:CF:13 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Weigao Nikkiso(Weihai)Dialysis Equipment Co.,Ltd.

- Take the first three octets of the address — in 64:CF:13:00:00:00 that is 64:CF:13 — 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.
