.aetna entered the DNS root zone on May 20, 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.
On the technical side, .aetna 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 .aetna, which lets validating resolvers check its answers cryptographically. Registration data is published over RDAP.
