Discuss relational for the high level redundancy employed in the DNS server architectural of the internet?

Well, recrusive DNS as we know it makes not finding a domain virtually impossible. There's not a whole lot to it, it'll just keep going, even though quite often it doesn't have to go _too far_. I think the internet wouldn't be half of what it is if there was a low level of redudancy and domain names jsut wouldn't resolve especially with IPv6 coming about.
