摘要：路由跟踪在线TracertTracert（跟踪路由）是路由跟踪实用程序，用于确定 IP 数据报访问目标所采取的路径。Tracert 命令用 IP 生存时间 (TTL) 字段和 ICMP 错误消息来确定从一个主机到网络上其他主机的路由。Tracert 工作原理 通过向目标发送不同 IP 生存时间 (TTL) 值的“Internet 控制消息协议 (ICMP)”回应数据包，Tracert 诊断程序确定到目标所采取的路由。要求路径上的每个路由器在转发数据包之前至少将数据包上的 TTL 递减 1。数据包上的 TTL 减为 0 时，路由器应该将“ICMP 已超时”的消息发回源系统。 Tra... 阅读全文
