"Ping", one of the eight DOS commands under Windows system with a high-force grid

ping command:

Ping is a basic command to detect whether a network is unobstructed or to query the speed of a network connection. As a computer-obsessed enthusiast, the ping command is the first DOS command to be mastered. It uses the principle of this: the machine on the network has a unique IP address, we send a packet to the destination IP address, the other side is going to return a packet of the same size, according to the returned packet we can determine the target host's existence, can initially determine the target host operating system and so on.

1. Ping/? : Queries the help on the ping command, which can be applied to most DOS commands. For example: NET/? ......
2. ping/t IP: The data table continues to occur to the destination IP until the destination IP is ping dead, unless you press CTRL + C to stop manually. "If you use 100M broadband to ping a kitten that is just 56KB, then it won't be long before the kitten goes offline because of the pressure of the packet,/funny, it's a simple DDoS attack."
3. PING/L: Defines the size of the packet that occurs, with a default size of 32 bytes and a maximum definition of 65500 bytes. "If this command is used in conjunction with the above command,/You know it!" 】
4. ping/n defines the number of packets that occur to the destination IP, which defaults to 3 "When we just want to detect if we can connect to the target IP, we just have to define 1 times, because three times is a waste of time." 】

Note 1: When PING/T is used in conjunction with/n 3, the ping command selects the following parameters to prevail! "

"Note 2:ping command does not have to add the target ip,ping host domain name is also possible. We will often use this method to obtain the target IP of the specified domain name "

Note 3: If ttl=128, the target host may be Win2000, if ttl=250, the target host may be UNIX, if ttl=32, the target host may be Win98, or if ttl=64, the target host is 64-bit system "
