ENS (Ethereum Name Service) is analogous to DNS (Domain Name System) for IP addresses, in that it maps a memorable shortcut to an address. ENS is a distributed, decentralized, open, and extensible naming system based on the Ethereum blockchain and a useful tool for developers to create more memorable names for their dapps.
An ENS name can be a subdomain of the root .eth domain, like "example.eth" or any subdomain of a subdomain, like "sub.example.eth", or "wallet.username.example.eth"
Using ENS we can map a friendly ENS name, e.g., "ethereum.eth", to an unfriendly Ethereum address, e.g., 0xfB6916095ca1df60bB79Ce92cE3Ea74c37c5d359. Users can then use the friendly name instead of the address, making it easier to remember, and reducing the chance of errors.
