What is .淡马锡?
Brand TLDs operate under Specification 13 of ICANN's registry agreement. It lets a trademark owner keep every second-level name for itself, so you won't find .淡马锡 names for sale at any registrar.
.淡马锡 entered the DNS root zone on January 24, 2015, 11 years ago. It came out of ICANN's New gTLD Program, the 2012 application round that grew the root from 22 generic TLDs to well over a thousand.
In the DNS, .淡马锡 is stored as the ASCII string xn--b4w605ferd (its "A-label"). Browsers and apps that support IDNs show the native script instead.
Temasek Holdings (Private) Limited also runs one other TLD, including .temasek.
On the technical side, .淡马锡 is served by 4 authoritative name servers, every one of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .淡马锡, which lets validating resolvers check its answers cryptographically. Registration data is published over RDAP and WHOIS (the WHOIS server is whois.nic.xn--b4w605ferd).
