.unicom domain extension

.unicom is a branded generic top-level domain owned and operated by China United Network Communications Corporation Limited, better known as China Unicom. This TLD is reserved for the company's internal use and cannot be registered by the general public. It was delegated in the root zone on February 1, 2016, following a previous registration date of January 22, 2016. While the registry offers no public registration services, it maintains its own WHOIS server at whois.nic.unicom and an RDAP server through ZDNS. The domain's technical infrastructure is managed by ZDNS, Ltd., based in Beijing, with a geographically diverse set of name servers. China Unicom, one of China's three major state-owned telecommunications operators, uses .unicom to reinforce its brand identity online.
