As of my training data up to September 2021, there is no top-level domain (TLD) by the name of .RSVP. Top-level domains or TLDs are the letters found at the end of an internet address (for example .com, .org, .edu, .gov and so on). The Internet Corporation for Assigned Names and Numbers (ICANN), the organization that oversees the distribution and organization of these domains, has not listed .RSVP as a recognized TLD.
ICANN divides TLDs into several categories: country-code TLDs (ccTLDs) like .us or .uk which are used or reserved for a country, sovereign state, or a dependent territory, generic TLDs (gTLDs) like .com or .org, and sponsored TLDs (sTLDs) like .gov which is used by U.S. government entities, and .edu which is used by post-secondary institutions accredited by an agency on the U.S. Department of Education’s list of nationally recognized accrediting agencies. In addition to these, there are also unsponsored TLDs, and infrastructure top-level domain.
As part of Internet services enhancement, ICANN started allowing a more extensive list of TLDs, including nearly any word or name, referred to as the New gTLD Program. As part of this program, hundreds of new TLDs have been, and can be proposed. These proposals undergo review before approval or rejection. Up until the latest update in my training data, .RSVP has not been among the proposed, approved or even rejected.
The closest used TLD is .rsvp, which has been documented to be used in phishing attacks. Phishing attacks are attempts by scammers to trick you into giving out personal information such as your bank account numbers, passwords and credit card numbers. However, it should be noted that this usage is illegitimate and not registered or recognized by ICANN.
RSVP is an acronym derived from the French phrase, “Répondez s’il vous plaît,” meaning “Please respond”. It is commonly used in event invitations to request that the invited person respond to indicate if they will be attending. As a TLD, it could potentially be useful for event planning or similar industries. However, until such a proposal is put forth and approved by ICANN, it does not exist as a valid TLD.
