Regular DNS systems are controlled by centralized entities like domain name providers and hosting companies. That means, authorities can subpoena these entities and gain control of whatever you're hosting, even if it's hosted elsewhere. As long as they can control the DNS, they can control you and what you publish to the internet. With dDNS, also known as "Distributed/Decentralized DNS", you're able to use dTLDs (.dweb, .web3, .dcom, .dnet, .dorg, etc), the decentralized cousin to TLDs (.com, .net, .org). dTLDs, unlike TLDs are free to register and manage and do not require a blockchain, although records are backed up through several DNS-ready blockchain networks, like dWeb's very own DNS-ready blockchain network - Telechain.
