HELP: ping www."host".com using arduino


can me how ping servers www.google.com , count number of request timed out reset device if got 30 consecutive or accumulated request timed out. reset number(request timed out) again. im having problems ethernet module enc28j60 doesnt reconnect itself  webserver/data logging server "iot-ph.com"  when adsl modem power cycled(turned off , on).

any input guys appreciated im totally new here in arduino , had little knowledge c++ since looks java
