There's nothing to scale. DNS servers are just an address book. There's only 200 million entries active and visited. 1.1b entries otherwise, which; for a computer isn't a lot.
DNS servers replicate down-stream, and the root servers maintain authority. A local SQLite file could handle this easily, and you could always run your own DNS server locally if you wanted to. But there has to be a central authority. That's why you can have any TLD you want -- you run your own DNS. But since nobody sees you as an authority, they won't be using your DNS.
