📗IZNSRegistry

The DomainRecord struct is meant to hold relevant information about a domain, such as its owner and resolver.

• owner (address): The owner of the domain (also called the owner of the Name).

• resolver (address): The address of the Resolver contract where this domain's source records are stored.

In the future, there will be multiple Resolver contracts that support different types of sources. Currently, only the ZNSAddressResolver is implemented.
