I recommend you spend some time trying to understand how the DNS system works before actually tryng to work with any implementation. > so if i want information about foo.com, then if it's not cached, i ask the > local caching-dns-server. it doesn't know, what is foo.com. so what does > it do? it asks the second name server? the 8.8.8.8?
