[Question] It is recommended to add resources to add devices through ip segments or subnets <title>

### Question

现在很多服务器、设备属于同一个ip段，通过导入导出还是比较麻烦，建议增加可以通过ip段或者子网添加设备，增加软件的易用性。

The issue proposes adding devices through IP segments or subnets instead of relying on import/export. Start by reviewing the existing device import/export flow, then clarify supported subnet formats, device-adding behavior, and completion criteria with maintainers. No files or tests are named in the issue.
