To the best of my knowledge, if a website has 20 images on it

of those 20. If you're not running a caching DNS server either on
that box itself or on your lan somewhere, then those 20 queries have
to go out to the DNS server you're using. At normal ISP speeds, that
can add up.

Isn't a DNS cache included in the browser or operating system already?
