Detailed analysis of route tracking command traceroute (1)
The premise for implementing all commands in this article is that you can access the Internet now.
People with a little computer knowledge know the ping command, which is used to check whether their host is connected to the target address, and the packet communication rate between their host and the target address, the so-called communication packa
Some might use route-tracking commands, but they don't quite understand the results shown. Let me give you a combination of my explanation.(1) Introduction of tracert commandThe tracert is a routing trace command that, through the return result of this command, can obtain the network devices that the local destination host has passed through.Usage: tracert [d] [-h maximum_hops] [-j host-list] [w timeout] Ta
Today's small series will give you to share my graduate students at the Northeastern University learned about the implementation of the route tracking, I hope that you read the small part of this blog post can be under the windows of the TRACERT command to have a certain understanding.
1. Experimental purpose
Tracert (Trace routing) is a route trace utility that
This article uses the GOOGLE tracking example to demonstrate how to perform the CMD operation and shows the tracking path. The following article provides detailed operation steps.
CMD command tracert xxx.xxx.com
For example, Google
C: \> tracert www.google.com
Tracing route to www.l.google.com [64.233.189.104]
Over a maximum of 30 hops:
1 11 MS 20 MS 19 MS 183.2.
Tracert: Route tracker that determines the path taken when an IP packet accesses a target and the latency of each hop in the IP network.Examples are as follows: The parameter-d means that IP addresses are not resolved to host namesC:\users\win7>tracert-d Projects.spring.ioUp to 30 hops trackingRoutes to Projects.spring.io [104.17.47.2]:1 2 4 ms 2 ms 3 ms 113.87.132.13 1 ms 1 ms 3 ms 113.106.43.1974 3 MS 3 ms 3 ms 183.56.67.1415 7 ms 7 ms 7 ms 183.56.6
First, the introduction of tools
Best Trace, from the official website of Ipip, currently has a version based on Mac, IOS, Android, and Windows systems, we can quickly from the local to the host of the route tracking, intuitive look at the line directly connected or winding.
Second, the tool downloads

Trace route usage:
Tracert [-D] [-H maximum_hops] [-J host-list] [-W timeout] [-R] [-s srcaddr] [-4] [-6] target_nameOption:
-D
Do not resolve the address to the host name.
-H maximum_hops
The maximum number of hops of a search target.
-J host-list
Loose Source Route (only applicable to IPv4) with the
We have used the ping command to check if the host is connected to the destination address, the communication packet communication rate of the host and destination address, the so-called communication packet, which is what TCP/IP,UDP packet.
about route tracking:The route trace directive is traceroute for Linux, and in Windows it is tracert, which is mostly traceroute.Traceroute is a tool used to detect the
The tutorial you are reading is: Dialysis ICMP protocol (5): Applying route tracing.
Principles:--------Through the introduction in the first four sections, you may have a preliminary understanding of ICMP applications. but before this section, I will introduce the ICMP protocol from a macro perspective. as we all know, ICMP is the third layer of iso-the network layer. Since it is at the same layer as the IP protocol, we may only use the IP protocol.
