<p>Hi Anurag,</p>
<p>Thanks for explaining, I absolutely get that. However, as I
mentioned earlier, I can't totally browse that particular site if
I use dual stack. My browser tries for a long time but gets
nothing. I checked many other sites with same configuration, they
are fine.<br>
</p>
<p>I don't understand if the problem is in my network or the remote
end.</p>

<div>In this browser will prefer IPv6 first. So browser will try
on IPv6, will wait for a while before it times out and falls
back to IPv4. </div>

<p>Hi Anurag,</p>
<p>Specifically, if you use dual stack, can you browse it
then?</p>

<br>
Those who are using dual stack, would you
please check if you can browse<br>
Malaysian High Commission's page <a
moz-do-not-send="true"
href="http://www.kln.gov.my/web/bgd_dhaka/home"
rel="noreferrer" target="_blank">http://www.kln.gov.my/web/bgd_<wbr>dhaka/home</a>
?<br>
<br>
When I use IPv4 only, it works fine. When I
use IPv6 only I can't browse<br>
the page, but it seems the website is IPv6
enabled.<br>
<br>
Surprisingly, if I use dual stack, I can't
browse the page which is the<br>
main problem I'm facing. I can't figure out
whether the problem is in my<br>
network or at their end. I'd really appreciate
if somebody help me<br>
through this?<br>
