The domain associated with “DIY” is not of a top-level domain (TLD) in the traditional sense of how Internet domain names are classified. A TLD is, in fact, the last segment of a domain. It is the part that follows immediately after the “dot” symbol. Examples of some well-known TLDs include .com, .org, .edu, .gov, and .net. These are also known as “generic” top-level domains (gTLDs).
Country codes such as .us, .uk, .ca and so forth are another category of top-level domains and are known as country code top-level domains (ccTLDs). More recently, ICANN, the organization responsible for maintaining and controlling these domain names, started a new program for creating and endorsing new gTLDs, which can be almost any string of characters. This new group of gTLDs comes with personalized names such as .travel, .food, .love, etc.
The domain “.diy” does not exist as a top-level domain as of the present moment according to the comprehensive list provided by the Internet Assigned Numbers Authority (IANA) which is a department of ICANN. IANA is in charge of overseeing global IP address allocation, DNS Root, media types, and other Internet Protocol-related symbols and Internet numbers. You can view the entire list of top-level domains in the Root Zone Database on the IANA website.
Though, if a TLD of “.diy” existed, it would theoretically fit into the category of new generic top-level domains (gTLDs), meaning it could potentially be used by sites that cater to the DIY (Do It Yourself) trend, similar to how the .food domain could be used by food-related websites or blogs. But again, as of now, no such domain exists.
Keep in mind that new gTLDs are subject to approval by ICANN, and acquiring a new gTLD is a costly and complicated process, as explained on the ICANN New gTLDs page. There are numerous rules and regulations that must be followed, including technical and operational standards, which are necessary to maintain the stability and security of the Internet’s domain name system.
To conclude, the “.diy” domain name could be a valuable tool for the DIY community if it were to be created and approved by ICANN in the future. However, as of the writing of this response, it does not exist as a top-level domain according to the official list of IANA.
