A top-level domain (TLD) is the last part of a domain name, which appears after the last dot (.) in the domain name. For example, in the domain name “example.com,” the top-level domain is “com.” TLDs identify the type of organization or entity that owns the domain, and the Internet Corporation manages them for Assigned Names and Numbers (ICANN).
Types of TLDs include:
Generic TLDs (gTLDs): These are not specific to any particular country or region, such as .com, .org, .net, .info, and .biz.
Country Code TLDs (ccTLDs): These are TLDs specific to a particular country or region, such as .us for the United States, .uk for the United Kingdom, and .cn for China.
Sponsored TLDs (sTLDs): These are TLDs sponsored by a specific organization or industry, such as .edu for educational institutions, .gov for government organizations, and .travel for the travel industry.
TLDs play an important role in the organization and navigation of the internet. They allow users to easily identify the type of organization or entity that owns a particular domain and help establish trust and credibility for certain websites.
