Definition ∞ A Top Level Domain, or TLD, is the last segment of a domain name, located after the final dot, such as .com, .org, or .net. TLDs form the highest level in the hierarchical Domain Name System of the internet. They are managed by organizations under the oversight of the Internet Corporation for Assigned Names and Numbers (ICANN). TLDs categorize websites and serve as a fundamental component of internet addressing.
Context ∞ While traditional TLDs are centrally managed, news in the digital asset space increasingly discusses blockchain-based Top Level Domains. These decentralized TLDs, often tied to specific cryptocurrency networks, offer censorship resistance and user ownership of domain names. The emergence of these alternative naming systems presents a challenge to the traditional internet governance model and offers new possibilities for digital identity and website hosting.
