The top-level domain (TLD) .CFD does not appear to exist in the current domain registry system. A TLD is the last segment of a domain name, the last label of fully qualified domain name. For instance, in the domain name www.example.com, “.com” is the TLD.
The Internet Assigned Numbers Authority (IANA) maintains a list of valid TLDs, and as of the time of writing, .CFD is not listed. IANA is responsible for the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. You can confirm the list of all TLDs that are currently delegated and recognized from the root zone database provided by the IANA (1).
The system of TLDs has expanded significantly from its original specific designations (.com, .edu, .gov, etc.) to include an array of “generic” (gTLDs) like .xyz or .ice, and “country-code” (ccTLDs) like .us or .ca. New TLDs can be added to the root zone as approved by the Internet Corporation for Assigned Names and Numbers (ICANN). ICANN is an internationally organized, non-profit corporation that has responsibility for Internet Protocol (IP) address space allocation, protocol identifier assignment, generic (gTLD) and country code (ccTLD) Top-Level Domain name system management, and root server system management functions (2).
As for the term “.CFD,” in a different context, it refers to “Contract for Difference.” CFDs are derivatives that enable investors to speculate on a wide range of financial markets, such as forex, indices, and commodities, without taking ownership of the underlying assets.
CFD trading is quite popular due to its various benefits such as accessibility, leverage, ability to go Long or Short, and diversity of markets. Investors should be aware that CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage (3).
The abbreviation “CFD” has several other meanings too; for example, in scientific and engineering contexts, it stands for “Computational Fluid Dynamics,” a branch of fluid mechanics that uses numerical analysis and data structures to solve and analyze problems that involve fluid flows (4).
Despite these various uses and meanings of the term “CFD,” at the time of my research, it is not represented in the TLD system.
