What ENS is
ENS is Ethereum's decentralised naming service, resolving names to addresses, content hashes and profile records. Names are ERC-721 registrations under the .eth registrar, extended by resolvers that map them to whatever a dApp needs.
Scope
The ENS contracts around name wrapping and registration: the NameWrapper, registrar controllers and resolver plumbing.
