Final answer:
TLDs are the highest level of domain names, including gTLDs like .com, .org, .net, and ccTLDs like .us, .uk, .cn. There are over a thousand TLDs managed by ICANN, and a complete list can be found on their website.
Step-by-step explanation:
Understanding Top-Level Domains (TLDs)
Top-Level Domains (TLDs) are the highest level of domain names on the Internet. They are found to the right of the domain name. It's not feasible to list all TLDs in this format because there are over a thousand TLDs, ranging from generic TLDs (gTLDs) like .com, .org, and .net, to country code TLDs (ccTLDs) like .us for the United States, .uk for the United Kingdom, and .cn for China. The Internet Corporation for Assigned Names and Numbers (ICANN) manages the TLDs and continually updates the list as new TLDs are added. To find the complete list of TLDs, you would need to visit the official ICANN website or a database that regularly updates TLD information.
