ENS (Ethereum Name Service) is a distributed, open, and extensible naming system based on the Ethereum blockchain.
ENS enables a user to associate a memorable .eth domain name with their public key hash.
The ENS is the same as the Ethereum wallet address that you have been using for different transactions. You can have your own ENS domain name like bitcoinexample.eth. Whenever people send funds to this address they will be routed automatically to your wallet without any confusion or errors such as when sending money to an exchange wallet not belonging to you.
You can find out where to claim your ENS on the board below:
