IP 选项记录路由要求沿途的路由器将其地址包含在数据报中，以便路线可以被追踪。诀窍是，许多路由器和防火墙并不热衷于给出此信息并DROP 设置了此选项的数据包。而且，您必须让远程对等点设置该标志，因此只有当您也控制远程对等点上的软件时它才有用。
The IP option Record Route asks routers along the way to include their address in the datagram so the route can be tracked. The trick is, many routers and firewalls are not keen on giving out this information and DROP packets with this option set. And, you'd have to get the remote peer to set the flag, so it would only be useful if you're in control of the software on the remote peer too.
