What is .sener?
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 .sener names for sale at any registrar.
.sener entered the DNS root zone on May 1, 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.
On the technical side, .sener 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 .sener, which lets validating resolvers check its answers cryptographically. Registration data is published over RDAP and WHOIS (the WHOIS server is whois.nic.rwe).
