How to Ping out the maximum size of a fixed size packet?
Ping -l 1000? The maximum value of Www.bb.com depends on the system, but it does not exceed 65535, and win7 is 65500.

Please note that a successful Ping does not necessarily mean that the TCP/IP configuration is correct, and it may be necessary to perform a lot of packet exchange between the local host and the remote host to ensure the correctness of the TCP/IP configuration.

If the ping is successful, but the network is still unavailable, the problem may be the software configuration of the network system. Successful ping can only ensure that there is a connected physical path between the current host and the destination host.

Extended data:

Implementation: ICMPPing.

ICMP is not only used to transmit error messages, but also used for message control messages. It is interdependent with IP protocol: IP uses ICMP when sending error or control messages, while ICMP uses IP to deliver messages.

ICMP messages are divided into information messages, error messages and control messages. Information messages are usually sent by clients, such as response request/response messages for testing the reachability of destination addresses.

This error message is usually sent by a server or router, indicating that the network or host cannot complete the required service. When sending an ICMP error message, the text always contains the IP header and the first 8 bytes of the IP datagram that generated the ICMP error message.

ICMP Ping means sending ICMP messages to the target host, and the target host (sometimes a router) responds to ICMP messages or error messages, and the Ping program knows the reachability of the target host according to these received ICMP messages. Available information messages are: response request and response message, timestamp request and response message and mask request and response message.
