Code:

  ping -c 1 ${IPADDRESS} >/dev/null 2>&1
  RESULT=$?   
  if [ ${RESULT} -eq 0 ]; then
    echo "INFO: Server ${IPADDRESS} is okay."
  else
    echo "WARNING: Server ${IPADDRESS} is NOT okay."
  fi
done

Result of running the above:
WARNING: Server 10.0.0.5 is NOT okay.
WARNING: Server 192.168.2.5 is NOT okay.
INFO: Server 127.0.0.1 is okay.

ping $host -n 1 | grep -q '1 packets received'
# here you can $host can be your dest ip/hostname

in a while loop you can read multiple hostname or ipadd from a file
