Ping is a important computer network administration utility; this tool is used to test whether a particular host is reachable across an Internet Protocol (IP) network and it measure the round-trip time for packets sent from the local host to a destination computer [including the local host's own interfaces]. When using this utility from pan-internet.com your "localhost" become our web server; this feature (changing the IP for where you send the ping) is very helpfully when you need to see from where is coming the reply of a computer. An example in this way is pinging a domain what has been changed the name server - untill replication is done requests to this domain will reply from diferent servers (old server or new server).
