Linux system, most of the students are used to test the network command tools, I use Windows10 system to test tracert
tracert: also known as Windows traceroute utility tracert used in a command prompt (cmd) may be used to route IP packets to determine the selected target access. This article discusses the various functions tracert command:
1. Enter "tracert" in the command line and an IP address is added in the back, you can be queried from the unit to a computer to go through from the IP address and the IP address of the router. IP address of the subsequent figures the IP address of another computer in the same LAN router:
2. The five pieces of information, respectively, from left to right represent the "time to live" (via a router node for each increment 1), "ICMP packet transmitted three return time" (total of three milliseconds ms) and " the router via IP address "(if there is a host name, will also include a host name):
3. You can also enter the back "tracert" pick a web site, DNS will automatically be resolved into an IP address and the router information via the probe. As this time is inputted after the URL address is almost known, it can be found in a total of 10 to query information, wherein the information with an asterisk (*) indicates that the packet is returned ICMP timeout times:
4. If you add the IP address does not exist in the "tracert" command, tracert program will be given. As shown below:
5. In the middle "tracert" command with an IP address or URL address entered "-d", may not resolve the IP address to the host name. As can be seen from the chart below, will add a "-d" do not show "PC-helei" words that do not display the host name:
6. In the middle of "tracert" command and enter the IP address or URL address "-h", and after adding a number, you can specify this tracert program searches for the maximum number of hops. After adding the following figure "-h 5", the search only to jump five times between routers, unconditionally ended:
7. 4 "," - 6 "represent the mandatory use of Ipv4 and Ipv6, I do know almost test site:
从上图可以看出，知乎使用的是Ipv4，不能用Ipv6。
