什么是 MAC 地址？
MAC 地址（Media Access Control Address）是网络设备的数据链路层标识符，也称为物理地址或硬件地址。它是一个 48 位（6 字节）的地址，通常表示为 12 个十六进制数字，如 AA:BB:CC:DD:EE:FF。
MAC 地址的前 3 个字节（24 位）称为 OUI（Organizationally Unique Identifier，组织唯一标识符），由 IEEE 分配给设备厂商，用于标识制造商。后 3 个字节由厂商自行分配，用于标识具体设备。
本工具可以指定起始 MAC 地址，按数量或终止地址批量生成连续递增的 MAC 地址列表。支持多种分隔符格式（冒号、连字符、点号、空格、无分隔、自定义），可导出为 CSV 文件。适用于网络设备批量配置、IPAM 系统地址规划、虚拟化平台 MAC 地址池管理等场景。
What is a MAC Address?
A MAC address (Media Access Control Address) is a data-link layer identifier for network devices, also known as a physical address or hardware address. It is a 48-bit (6-byte) address, typically represented as 12 hexadecimal digits, e.g., AA:BB:CC:DD:EE:FF.
The first 3 bytes (24 bits) of a MAC address are called the OUI (Organizationally Unique Identifier), assigned by IEEE to device manufacturers. The last 3 bytes are assigned by the manufacturer to identify specific devices.
This tool generates sequential MAC address lists from a starting address, either by count or by end address. Supports multiple separator formats (colon, hyphen, dot, space, none, custom) and CSV export. Useful for batch network device configuration, IPAM address planning, and virtualization platform MAC pool management.
