I’m afraid there appears to be a misunderstanding, as “FIDO” is currently not a recognized or registered top-level domain (TLD). TLDs are the last segment of a domain name, the part that follows immediately after the “dot” symbol. Common TLDs include .com, .net, .org, .gov, and .edu, among others, and they can also be specific to a country, such as .us, .uk, .fr, etc.
The Internet Assigned Numbers Authority (IANA) is responsible for the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. This includes the delegation of top-level domains. A visit to their site (https://data.iana.org/TLD/tlds-alpha-by-domain.txt) can provide an up-to-date list of all the currently delegated TLDs, and FIDO currently does not appear there.
However, the term “FIDO” often refers to the Fast IDentity Online alliance (FIDO Alliance), an industry consortium that was launched in February 2013 to address the lack of interoperability among strong authentication devices. The FIDO alliance aims to develop specifications for a standard, open, scalable, and interoperable set of mechanisms that reduce the reliance on passwords to securely authenticate users of online services (source: https://fidoalliance.org/overview/).
It’s important to clarify that while it is indeed feasible for entities or organizations such as FIDO to apply for a TLD matching their name, the process involves a thorough review by ICANN (the Internet Corporation for Assigned Names and Numbers). The proposal could be rejected for a variety of reasons, including the potential to infringe on a trademark, create confusion, or if the entity cannot demonstrate the necessary technical and financial capabilities.
For instance, the brand “.google” is a brand TLD, reserved solely for Google’s use (source: https://www.icann.org/resources/pages/google-2014-02-06-en). Hence, it’s possible that FIDO Alliance could apply for a “.fido” TLD if it meets ICANN’s specific requirements and goes through that rigorous process.
In conclusion, while “FIDO” may refer to a significant industry consortium in online security, it is not a current recognized top-level domain. As technology and the internet continue to evolve, the list of TLDs continues to expand, and it may be possible that .fido could become a TLD someday, subject to ICANN’s rules and requirements.
