eero inc. 有多少个 MAC 地址前缀（OUI）？

根据 IEEE 官方注册库，eero inc. 共注册了 108 个 OUI / MAC 地址前缀，例如 00:AB:48、08:9B:F1、08:F0:1E 等。

如何判断一个 MAC 地址是否属于 eero inc.？

取 MAC 地址的前缀（前 6~9 位十六进制）与本页列出的 eero inc. 前缀比对即可；也可直接使用 MAC 地址厂商查询工具自动匹配。

MAC地址厂商查询的数据来源是什么？

数据来自 IEEE 注册管理机构（Registration Authority）公开的 OUI/MA 数据库，包含 MA-L（24位）、MA-M（28位）、MA-S（36位）三张表，本工具按最长前缀优先匹配以保证准确归属。

支持哪些 MAC 地址格式？

支持冒号、连字符、点分以及无分隔等任意写法，例如 00:1B:44:11:3A:B7、00-1B-44-11-3A-B7、001b.4411.3ab7，大小写均可。也可只输入前 6 位或更长的前缀。

为什么有些 MAC 地址查不到厂商？

若 MAC 的第一个字节 U/L 位为 1，则属于本地管理地址（如虚拟机、随机化 MAC），并未在 IEEE 注册，自然查不到厂商；此外极少数新分配前缀可能尚未收录。

单播、多播、本地管理是什么意思？

MAC 第一个字节的最低位（I/G 位）为 0 表示单播、为 1 表示多播；次低位（U/L 位）为 0 表示全局唯一（由 IEEE 分配 OUI），为 1 表示本地管理。全为 FF 则是广播地址。

数据是否安全？会被上传吗？

查询仅把 MAC 前缀发送到本站接口做厂商匹配，不保存任何记录；属性解析在本地浏览器完成，隐私安全。

关于 eero inc. 的 OUI

OUI（Organizationally Unique Identifier）是 IEEE 分配给设备制造商的地址前缀。一个 MAC 地址若以上表中的任一前缀开头，通常即由 eero inc. 生产或贴牌。

注册类型决定前缀长度与可用地址数：MA-L 占 24 位（约 1678 万个地址）、MA-M 占 28 位、MA-S 占 36 位（4096 个地址）。判断归属时应按最长前缀优先匹配。
