Reading the "header" of such ane-mail, the part of the message documenting its route over the Internet from sender to receiver, to determine who really sent it is one way to spot a scam.
只建立一条路径，浪费掉了多数路由发现报文形成的路径信息。

若不能发现详细准确的网络信息，仅对网络的增长感兴趣，可选用基于DNS协议路由表的拓扑搜索；
If can't find the detailed and accurate network information, is only interested in the growth of the network, can select the topological search based on DNS agreement route form for use;
现有网络拓扑发现方法依赖于路由信息的完整，网络中大量存在的路由信息残缺情况往往导致拓扑发现的失败。
The existing network topology discovery methods require intact routing information, but a lot of routing information lack instances in network make them fail.
