Short menu domain12/18/2023 ![]() "Dotless names would require the inclusion of, for example, an A, AAAA, or MX, record in the apex of a TLD zone in the DNS (i.e., the record relates to the TLD-string itself)," states ICANN's older announcement. In 2013, the internet regulatory authority ICANN adopted a resolution banning dotless domain names and stating that their usage could be harmful as such domains are usually expected to resolve in a local context (i.e. For example, heading over to or may present valid websites-viewable by only staff and users on the corporate network.īut, when it comes to the world wide web, this practice is neither widely prevalent nor encouraged. In internal networks typically implemented by enterprises, it isn't unusual to have dotless domains reachable from within the company. On a Samsung smartphone, using Chrome for Android and the mobile network operator's DNS settings posed no issues when visiting either domain. On Windows, our attempts to access pn/ and ai/ using a variety of web browsers (Chrome, Firefox, and Brave) did not always succeed, when tested with both ISP's DNS settings as well as DNS services from Cloudflare (1.1.1.1) and Google (8.8.8.8). Safari on macOS does not recognize the website (BleepingComputer) Previously an American citizen, Cate states that in 1994 he relocated to Anguilla, a British Overseas Territory that holds the rights to the ai TLD domain which Cate is involved in managing . In tests by BleepingComputer, visiting in Google Chrome on macOS presented a valid webpage, that can otherwise also be reached at: Īs for Vince Cate, the cryptographer and software developer who owns and operates the offshore.ai domain, there's a little history lesson on his website. Although not all TLDs may show a web page when entered in a web browser, some of them do. Williams gathered a list of TLDs that have valid DNS A records. ![]() "For example, if Verisign (the operator of the com TLD registry) wished, they could add an A record at the apex of the com TLD zone – com would then resolve to that IP, and your browser would connect to that IP when you visited "Does any registry operator actually do this though? Surprisingly, the answer is yes." "There's nothing stopping TLD registry operators serving A records at the apexes of their TLD zones," explains Williams in a succinct blog post from last month. Had that been the case, navigating to present the user with a web page. In theory, for example, it would be possible for internet regulatory authorities to enable top-level domains (TLDs) like com to be a valid domain by itself and have valid DNS records resolving to a server. London-based software engineer James Williams has steered everyone's attention towards domains that are even shorter than the widely known g.co or m.me.Īlthough the vast majority of internet domains contain TLDs separated by one or more dots, turns out it's not a must for a domain. You may be familiar with some of the shortest internet domains used by major companies, such as m.me and fb.me from Facebook (Meta) and Twitter's t.co URL shortener.īut, it's possible for live domain names to be even shorter than these choices-and contain no dots.
