When you send a ping request to another host just like a sending an echo packet to the another host....if that host connected with you in the internet then..that will reply you....that the connection is there......and technically speaking when you ping with an IP address...then that IP address will reply you.....

When you ping one ip address, that time your machine will send echo request (type 8 code 0 ) message to respective destination ip address. Upon receiving echo request, respective ip address (machine/server) will reply with echo reply(type 0 code 0) message to let you know its presence in this way ping works.

The ping application generates ICMP echo packets from host 1 which when reaches host 2 checks for connectivity and returns with the result back to host 1.
