Reverse Registrar

Reverse resolution, the process of mapping an address (e.g., 0x1234...) to a .vet name, is managed through a special namespace, .addr.reverse. This namespace is controlled by a specialized registrar, as outlined in EIP 181, which assigns subdomains to callers based on their address.

For instance, the account 0x314159265dd8dbb310642f98f50c066173c1259b can claim the subdomain 314159265dd8dbb310642f98f50c066173c1259b.addr.reverse. Upon claiming, it can set up a resolver to reveal metadata, including a canonical name for the address.

The reverse registrar offers functions to claim a reverse record and a convenience function (setName) for setting up the record. The latter is primarily used to assign a canonical name to an address.
