检测IP类型，是否是原生IP。

什么是原生IP？

原生 IP 是指其注册国家与 IP 所在机房或实际地理位置国家一致的 IP 地址。大部分家庭宽带 IP 属于原生 IP，部分本地 IDC 服务商也会使用原生 IP。

而一些全球性的跨国 IDC 服务商（如 AWS、GCP、Azure 等）为了便于管理，通常会购买较大的 IP 段，并将其广播至不同国家，这类 IP 被称为广播 IP。

因此，当一个 IP 被标记为原生 IP 时，通常表示该 IP 是家庭宽带 IP 或本地 IDC 提供商的 IP；而当被标记为广播 IP 时，则表明该 IP 不属于家庭宽带或本地 IDC 提供商。

当一个 IP 显示 为广播 IP 时，通常代表这是一个 非家庭宽带 IP，非本地 IDC 提供商 IP。
