MAC Prefix List

Netify vs. IEEE OUI Official Name
The IEEE OUI official organization name comes directly from ieee.org. In addition to the verbose legal suffixes (e.g. Co. Limited), there are some inconsistencies in punctation, capitalization, spacing, and styling. We provide a more user-friendly Netify Vendor Name as an alternative.
Scope: Global vs Unique
MAC addresses can be a globally unique address (i.e. there's only one on the entire planet), or a randomized local address. Most IoT, media, and industrial devices use globally unique addresses. However, many mobiles, tablets, and laptops use local randomized MAC addresses to maintain privacy on public networks.
