DNS Cache?

Can anyone explain what clening up the DNS Cache does?

Thanks!

DNS Cache - When you visit a Web site, Windows attempts to speed up future visits to that site by writing its DNS information to the DNS cache. This option will clear out the cache so that Windows can start storing DNS information from scratch.

I'd say it does the same as if you'd run ipconfig/flushdns
