What is .citi?
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 .citi names for sale at any registrar.
.citi entered the DNS root zone on July 28, 2016, 10 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.
Citigroup Inc. also runs one other TLD, including .banamex.
On the technical side, .citi is served by 6 authoritative name servers, every one of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .citi, which lets validating resolvers check its answers cryptographically. Registration data is published over RDAP.
