DNS NoSQL store
A NoSQL experiment treats names in a DNS zone as hierarchical keys and their records as values, while inheriting DNS caching and update semantics.

Records in a DNS zone can be viewed as values reached through hierarchical keys. This experiment pushes that idea toward a generic data-store model.
The analogy is useful, but DNS has very different consistency, authority, cache, and size rules from a conventional database.
