关于自治系统 (ASN)
自治系统 (ASN) 是一个唯一的数字标识符，用于在互联网上识别一个大型网络群体（称为自治系统 AS），这些网络群组由单一组织管理并遵循共同的路由策略，通过 BGP (边界网关协议)与其他自治系统交换路由信息，就像是互联网上的"身份证号"或"门牌号"，方便全球路由器识别和转发数据包。例如，Google (AS15169)和Cloudflare (AS13335)都有各自的ASN。
自治系统 (AS) 的概念
定义：一个或多个实体管理的 IP 网络和路由器集合，这些网络遵循统一的路由策略。
管理：通常由一个互联网服务提供商 (ISP)、大型企业、云服务商或政府机构管理。
路由：内部使用内部网关协议 (IGP) 路由，但与外部网络通信时，通过 BGP 协议交换信息。
