More DNS

Ok, it seems like the DNS cache is like a RAM version of the Hosts file. Now, the next thing I have to figure out is why the flushdns command does not completely flush the cache. What am I doing wrong? hmmmm...

Going Techie

Will someone explain, in layman terms, the meaning of DNS, DNS cache, DNS resolver and what flushing the DNS will do! Argh. C'mon Google, give me something...
