My apologies, but I couldn’t find any reference to a top-level domain (TLD) known as .UNICOM. It’s important to note that all TLDs are governed and managed by the Internet Assigned Numbers Authority (IANA), the organization responsible for the global coordination of the DNS root, IP addressing, and other Internet protocol resources. This entity is a department within ICANN (Internet Corporation for Assigned Names and Numbers), a non-profit organization that oversees the use of all domain names and IP addresses globally.
The highest level of domain names in the Root Zone Database, maintained by IANA, are the Top Level Domains, which include generic Top-Level Domains (gTLDs), country-code Top-Level Domains (ccTLDs), internationalized Top Level Domains (IDN-TLDs), and infrastructure Top Level Domain (.arpa).
Generic Top-Level Domains (gTLDs) comprise domains such as .com, .org, .net, .edu, etc., while Country Code Top-Level Domains (ccTLDs) include .uk for the United Kingdom, .us for the United States, .fr for France, and so on. The IDN-TLDs are for the domains catering to non-English languages incorporating specific diacritic marks, non-Latin scripts, etc.
As of today, the .UNICOM TLD does not exist, according to the Root Zone Database by IANA (https://data.iana.org/TLD/tlds-alpha-by-domain.txt). There’s a procedure for proposing new TLDs, which involves a round of applications, the previous one having been in 2012, when extensions such as .app, .xyz, .online, etc., were launched.
“UNICOM” might refer to UNICOM Global, a US-based global IT provider or could be an internal network domain for an organization named Unicom, but it isn’t a recognized global TLD.
However, as mentioned above, ICANN periodically opens application periods for new gTLDs, so it’s possible that .UNICOM might become a future TLD if a legitimate entity such as UNICOM Global perceived a need for it and decided to apply.
For now, the information about new application periods is yet to be announced by ICANN, and until they sanction the .UNICOM TLD, it will not be recognized or available in the domain name system’s hierarchy. Thus, any use of .UNICOM as a TLD outside of the global domain name structure would not be visible or accessible on the wider internet.
