You could well be right -- a lot of DNS servers out there do not
respond correctly (or even at all) to queries for  or A6 records.
You can confirm if that is the case by using tcpdump to show you what
DNS traffic your system is generating as you browse around.

This is a case of FreeBSD users being penalised for running a properly
standards compliant OS by stupid service providers who are unable to
install standards compliant DNS servers with support for RR types
introduced getting on for 10 years ago now.  Even worse, DNS servers
that don't return any response to such a request, which forces your
system to wait for the whole 30s of the DNS timeout.

Cheers,

Matthew

Hello,

Have a look at the different ad.doubleclick.net addresses included in the web site.

Find out the ip address and put them in your /etc/hosts file like this:

206.65.183.95   ad.doubleclick.net
206.65.183.95   uk.doubleclick.net
206.65.183.95   ad.uk.doubleclick.net
195.154.195.154 ad.fr.doubleclick.net


This will solve the loading time of the different websites with konqueror, firefox 
etc( sticking to load 90% of the images of the web site). 
This issue doesn't seem to exist when you use Opera. 


Kind regards

Jens
