Does this cache have to be cleared? I don't know the solution to your overall problem, but IIUC, DNS results are not cached by a basic linux system, unless you're running a caching DNS application, such as dnsmasq. To see if caching is happening, one runs 'dig some_site' twice in a row. If caching is happening, the second "Query time:" should be 0, while the first will be some number of milliseconds (unless, of course, the domain is already in the cache). Without caching, all queries should have a non-zero query time. Of course, there could be caching taking place somewhere upstream of your box.
