Tracert tracks the network path and tracert tracks the path

Tracert command Introduction

The Tracert command uses the ip ttl field and the ICMP error message to determine the route from one host to other hosts on the network.

Command Format:

Tracert [-d] [-h maximum_hops] [-j host-list] [-w timeout] [-R] [-S srcaddr] [-4] [-6] target_name

-D specifies not to resolve the address to the computer name.

-H maximum_hops specifies the maximum number of hops of the search target.

-J host-list: A loose source route that is used together with the host list (only applicable to IPv4 addresses). It specifies that the route is forwarded in the descending order of the host-list sparse source route list. Host-list is a list of up to 9 vro IP addresses separated by spaces.

-W timeout: the timeout time (in milliseconds) for each response ).

-R: tracks the round-trip path (only for IPv6 ).

-S srcaddr source address (only applicable to IPv6 ).

-4. Use IPv4.

-6 forcibly use the name of the target computer using IPv6.target _ name.

Tracert is used to track the access path from school to website:

1. First view your IP address

The school uses ruijie certification, and the IP address is dynamically allocated 115.156.208.62

2. Trace the path to www.baidu.com

> Tracert www.baidu.com

> Tracert www.taobao.com

3. Analyze the path to access www.baidu.com

As you can see, accessing www.baidu.com finally points to an IP address in Beijing. Taobao.com sets a cache image in Wuhan Education Network, and the access to Wuhan education network is redirected to the cache machine room set up by Wuhan Education Network.
