Of course it can't, this is a problem that is a result of design decisions for 
browsers and browser plugins (mostly plugins), in most (all?) cases the DNS 
is functioning as designed.

One might mitigate some of these attacks, by subverting the DNS, and avoiding 
responses with short TTL, but down that path lies madness - since one is 
trying to fix a browser problem at a lower level.
