What is .unicom?
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 .unicom names for sale at any registrar.
.unicom entered the DNS root zone on February 4, 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.
China United Network Communications Corporation Limited also runs one other TLD, including .联通.
On the technical side, .unicom is served by 8 authoritative name servers, 2 of them reachable over IPv6. It is also DNSSEC-signed: the root zone carries a DS record for .unicom, which lets validating resolvers check its answers cryptographically. Registration data is published over RDAP and WHOIS (the WHOIS server is whois.nic.unicom).
