</span>That query went un-answered. The answer would be after the QUESTION<br>
section. The server it asked (192.168.1.1) didn't have any data to give<br>
back to the query.<br>

</span>The malformed warning doesn't sound good.<br>

</span>That one did have an answer: <a href="http://Fujiantonio.homenet.telecomitalia.it" rel="noreferrer" target="_blank">Fujiantonio.homenet.telecomitalia.it</a>.<br>
<br>
And if DNS is fully working, doing a dig against the name, should come<br>
back with the same IP.<br>
<br>
Is that a domain that you own, or has the query gone through to your<br>
ISP? (If 192.168.1.1 didn't know the answer, it can ask further up the<br>
chain.)<br>
<br>
If I do a "dig <a href="http://telecomitalia.it" rel="noreferrer" target="_blank">telecomitalia.it</a>" I get a public IP. If you're<br>
shoehorning your LAN into your ISP's domain name, or anybody else's<br>
domain name, you're likely to strike problems.<br>

</span>Again, no answer was forthcoming from that DNS server. It won't really<br>
matter where you do the query from (the same PC as the server, or over<br>
your LAN).<br>
<br>
What's 192.168.1.1? A computer or a router?<br>
