You may check communication with computer or look up if a host is online by executing a ping command. Windows does not provide graphical utility to do that, but has a command line tool. This software works just like command line ping.exe but has a configurable parameters screen and a nice graphical output. You may preset TTL - time to live of the ICMP packet to be sent, the size of the ICMP packet to send, number of ping requests, host name resolution option, packet size. The software can run both using ICMP or WinSock. You may export ping resulat or print them out right from Network Ping.
