DNS caching/lookup in Konq or KDE?

[John]

While trying to find out why ebay and other pages took ages to load and dns 
services sometimes misbehaved (eg Can't find ebay search) I took a look at 
what was going on with ethereal.
Essentially whenever there is any eth0 activity going to the web or an arp 
from the router something inserts a number of unrelated dns requests into and 
after the transmission. They are always for servers that I have browsed 
recently.

Is this normal operation? 

My concern is that it's caused by something that has found it's way on to my 
machine.
If it is konq refreshing some sort of dns cache/lookup how do I turn it off 
and is there any way of playing with it's settings?

I have the main cache turned off. It would need to be very large to be of much 
use and I wonder about the relative efficiency with modern high line speeds.

Regards
John
