I’m sorry, but as of my current knowledge and according to the data up to 2022, there is no top-level domain (TLD) .KOSHER.
Top-level domains (TLDs) are the last segment of a domain name – the letters that come after the final dot, for example, .COM, .ORG, .NET, and so on. They are categorized into generic top-level domains (gTLDs), country-code top-level domains (ccTLDs), which usually have two letters, and infrastructure top-level domain (.ARPA). There are also sponsored top-level domains (sTLDs) that are supervised by private organizations.
The list of TLDs whether gTLD, ccTLD or sTLD is maintained and updated by the Internet Assigned Numbers Authority (IANA), which is a function of ICANN. ICANN stands for the Internet Corporation for Assigned Names and Numbers. This body is responsible for coordinating and ensuring the stable operation of the internet’s unique identifier systems – essentially keeping the internet running smoothly.
ICANN has been periodically expanding the list of gTLDs. New gTLDs can be proposed and if approved, they become available for registration of domain names. Some of the examples of these new gTLDs include .APP, .BLOG, .EMAIL, among others. Enterprises and organizations can propose new gTLDs. Google, for instance, operates the gTLD .GOOGLE.
However, as of 2022, there is no .KOSHER TLD available or being proposed – at least, not publicly. This information can be verified via the IANA’s TLD list, available on the IANA’s official website (https://data.iana.org/TLD/tlds-alpha-by-domain.txt). In other words, no website can currently have a web address ending in .KOSHER.
If the TLD .KOSHER were to be proposed, it would likely have to go through an application process with ICANN, which includes a public comment period and other evaluation processes to ensure the TLD is not confusingly similar to an existing TLD, doesn’t infringe on intellectual property rights, and is otherwise in the best interest of the internet community.
However, please note that the availability of TLDs can change over time as new domains are proposed, approved, or retired. Therefore, the information given here is subject to change and should be checked periodically if .KOSHER is of particular interest.
In conclusion, there currently is no .KOSHER top-level domain in the list of IANA TLDs.
