A domain name always includes a top-level domain (TLD) as part of its structure, which is the last part of the domain name following the final dot. TLDs include common extensions such as .com, .org, and .net, as well as country-specific extensions such as .uk, .ca, and .au.
It is not possible to register or use a domain without a TLD. In fact, the TLD is a critical component of a domain name, as it helps to identify the type of organization or geographic region that the domain is associated with.
If you are attempting to enter a domain name without a TLD into your web browser, the browser will likely produce an error or return a message indicating that the domain is not valid. Similarly, if you are attempting to register a domain without a TLD, most domain name registrars will not allow you to complete the registration process.
