I’m sorry, but there seems to be a misunderstanding. Currently, there is no top-level domain (TLD) with the name “.cheap.” A top level domain (TLD) is the last segment of a domain name, or the part that follows immediately after the “dot” symbol. TLDs are mainly classified into two categories: generic TLDs and country-specific TLDs. Examples of some of the most popular TLDs include .com (commercial), .org (organization), .net (network), .gov (U.S. governmental), .edu (educational), .eu (European Union), .ru (Russia), .cn (China), and many others.
There are also more specific or niche TLDs, such as .info, .biz, .mobi, .name, etc. Even with these, though, there is no TLD such as .cheap. This information is corroborated by the Internet Assigned Numbers Authority (IANA), which provides a TLD listing on their website (source: https://data.iana.org/TLD/tlds-alpha-by-domain.txt). The IANA is a department of ICANN, the Internet Corporation for Assigned Names and Numbers, which is a nonprofit organization responsible for coordinating the maintenance and procedures of numerous databases related to the namespaces and numerical spaces of the Internet, thus ensuring the network’s stable and secure operation (source: https://www.icann.org/).
With that said, it should be noted that new TLDs can be created. ICANN began a new program in 2011 to expand the number of generic TLDs (gTLDs). This New gTLD Program has, over several application rounds, remarkably increased the number of gTLDs from the initial 22 to over 1,200. The list of these new gTLDs includes many different kinds of names such as .hotel, .love, .money, .music etc. However, these TLDs are not on the same popularity level as traditional ones like .com, .org, etc., due to various reasons. First, they are relatively new and not widely recognized by the public. Secondly, registering these new gTLDs might present a more substantial financial burden for the registrants.
If there were interest in a .cheap TLD, the application process to create a new gTLD is extensive and costly, requiring a significant application fee as well as ongoing costs and evidencing the ability to technically and administratively support the TLD. Furthermore, there is typically a period of public commentary and potential objection to proposed new gTLDs. It would be a significant undertaking (source: https://newgtlds.icann.org/en/).
In summary, to this date according to reputable sources such as ICANN and IANA, no “.cheap” TLD currently exists. If it were to exist in future, it would need to be proposed, accepted, and established through the complex ICANN new gTLD program.
