Every domain name must have a top-level domain (TLD) extension, 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 have a valid domain name without a TLD extension. The TLD extension 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 attempt to enter a domain name without a TLD extension 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 attempt to register a domain name without a TLD extension, most domain name registrars will not allow you to complete the registration process.
