First : hostip.info rocks !!

Well, when I browse the home page (http://www.hostip.info/) my city is mentioned. Not necessary correct but it's mentioned.
But when I use an url like this : http://api.hostip.info/get_html.php?ip=81.249.58.165
Here is the result :
Country: FRANCE (FR)
City: (Unknown city)
Does it means you're using inproved api to display your result on the home page ?
Or maybe it's because you're using a rough-html But I get a 404, each time I used rough_html.
Best,
