Thank you very much. One doubt I have, when I provided my IP address, the KML file is only contains this:

<?xml version="1.0" encoding="UTF-8"?>

<kml xmlns="http://www.opengis.net/kml/2.2">

<Document>

<Style id="transBluePoly"><LineStyle><width>1.5</width><color>501400E6</color></LineStyle></Style></Document>

</kml>

But if the IP address is x.xxx.xxx.xxx, then its giving proper output. could you please tell me the reason?
