How to find the current owners of ENS domains

Basically there are two types of ENS domain owners, those who bought the domain directly from ENS and those who receieved the domains from other owners. In both cases, there are sub transactions within the transfer transactions.

However, the last sub-transaction is always between 0x283af0b28c62c092c9727f1ee09c02ca627eb7f5 and the new owner.

Therefore, I tried to get the latest transaction transferring a token of ENS domain from 0x283af0b28c62c092c9727f1ee09c02ca627eb7f5 to the owner.

Next step, I can get the number of wallets which have only one ENS domains and the number of wallets which have multiple ENS domains.

From the query results, the number of wallets with only one ENS domains is around 3 times bigger than the number of wallets with multiple ENS domains
