As of my current research up to March 15, 2022, the “.EXTRASPACE” top-level domain (TLD) does not exist in the Domain Name System (DNS) of the Internet. Top-level domain names are the suffixes or the last part of a domain name managed by certain organizations under the supervision of the Internet Corporation for Assigned Names and Numbers (ICANN). Currently, there are more than 1500 TLDs, including country-specific domains (like .us for United States, .uk for United Kingdom), generic top-level domains (gTLDs like .com, .net, .org), or sponsored top-level domains (sTLDs like .aero, .edu, .mil).
New top-level domains can be applied for through ICANN’s New gTLD Program. Organizations interested in managing a TLD must undergo an application and evaluation process that includes background checks and technical capability assessments, as outlined in the ICANN Applicant Guidebook.
Notably, each proposed top-level domain name must not conflict with any existing TLDs and must comply with DNS naming conventions. Specifically, it must not exceed 63 characters and only contain letters, digits, and hyphens. This process is aimed at preserving the reliability and stability of the internet by ensuring proposed TLDs will not disrupt existing internet names and resources.
As per the ICANN site’s current list of delegated registry agreements and the IANA’s Root Zone Database, there is no record for a “.EXTRASPACE” TLD. However, similar TLDs do exist, such as “.SPACE”, which is managed by the Radix Registry and caters to individuals and businesses involved in space industries or looking for a creative space online for their presence.
In any case, should an organization wish to establish and operate a new “.EXTRASPACE” TLD for their own purposes, they can follow ICANN’s processes for new top-level domain applications once the application window opens again.
For future references, please note that ICANN provides updates and information for the general public through its website, while IANA maintains a comprehensive Root Zone Database that identifies all current TLDs. Furthermore, individual domain registrars and resellers often offer searchable databases, where existing domain names could be searched.
In conclusion, currently, the “.EXTRASPACE” top-level domain does not exist. Nevertheless, a process does exist through ICANN for organizations to apply for new TLDs, once applications are open.
