路由追踪

追踪从我们的服务器到任何 IP 地址或域名的网络路径。查看每个跃点，测量延迟，识别路由问题或网络瓶颈。

路由追踪如何工作

路由追踪是一种网络诊断工具，显示数据包从源到目的地所经过的路径。它通过发送递增生存时间（TTL）值的数据包来工作。

理解结果

• 跃点编号： The sequential step in the route (1 = first router, 2 = second, etc.).
• IP 地址： The IP of the router at that hop.
• 主机名： The reverse DNS name of the router (if available).
• 延迟： The round-trip time (RTT) in milliseconds. Lower is better.
• * * *: Indicates the router at that hop did not respond (timeout).

这个工具如何工作？

此工具从我们的服务器执行路由追踪到您指定的目标 IP 或域名。它发送递增 TTL（生存时间）值的数据包，记录沿途响应的每个路由器。结果显示每个跃点的 IP 地址、主机名和延迟。

请注意，此路由追踪从我们的服务器位置执行，而非您的本地机器。由于不同的网络路径和距离，您看到的路径和延迟将与本地路由追踪不同。

为什么要使用路由追踪？

• 网络诊断： Identify where network connectivity issues occur between two points.
• 性能分析： Find which hop in the route is causing high latency.
• 路由验证： See if traffic is taking the expected path through the network.
• 故障调查： Determine if a connectivity problem is local, regional, or at the destination.

如何解读结果

1. 低且一致的延迟： Healthy network path — packets are traveling efficiently.
2. 突然的延迟尖峰： Possible congestion, overloaded router, or long-distance hop.
3. Timeouts (* * *): The router at that hop is not responding to traceroute probes. This is common and doesn't always indicate a problem.
4. 最终跃点不可达： The destination may be down, blocking ICMP, or behind a firewall.

检测到的常见问题

• 高延迟尖峰： A sudden increase in latency at a specific hop may indicate congestion or a routing issue.
• Timeouts (* * *): Routers may be configured to not respond to traceroute packets. This is normal and doesn't always indicate a problem.
• 路由环路： If the same IP appears at multiple hops, there may be a routing loop.
• 非对称路由： The return path may differ from the forward path, which is normal but can complicate troubleshooting.

限制

This traceroute is performed from our server, not from your local machine. The path and latency will differ from what you'd see locally. For a local traceroute, use your operating system's built-in tools (tracert on Windows, traceroute on macOS/Linux).
