Network Connection Test Commands 451 ■ host will be treated as IP address first. If it is not an IP address, perform domain name resolution, ■ the default padding operation starts from 0x01 and ends on 0x09 (progressively), then performs again, ■ show all the information including statistics, ■ routes are not recorded, ■ send ECHO-REQUEST according to route selection, ■ default length of ECHO-REQUEST is 56 bytes., ■ default timeout of ECHO-RESPONSE is 2000ms, ■ do not display other ICMP packets (non ECHO-RESPONSE), ■ the TOS value of echo requests is 0. The ping command sends ICMP ECHO-REQUEST message to the destination. If the network to the destination works well, then the destination host will send ICMP ECHO-REPLY to the source host after receiving ICMP ECHO-REQUEST. Perform the ping command to troubleshoot the network connection and line quality. The output information includes: ■ Responses to each of the ECHO-REQUEST messages. If the response message is not received until timeout, output "Request time out". Or display response message bytes, packet sequence number, TTL and response time. ■ The final statistics, including number of sent packets, number of response packets received, percentage of non-response packets and minimal/maximum/average value of response time. If the network transmission rate is too low to increase the response message timeout. For the related commands, see tracert.
