$10/year is super expensive for the cost of linking few thousands of requests to an IP address. The point of my question was: who has obscene margins ?

So if it is the guys who owns the TLDs who rip everyone off, if a company bought a TLD and started to rent it at production price, it would finally enable domain names at like one cent or one dollar? (most websites have like 10 requests and they have a single IP, I don’t get why one cent would be impossible)
