TLDs or domain suffixes are the mandatory part of domain names that come after the dot and better represent the site’s purpose, objective, or geographic region. For example, .gov for governments, .edu for educational websites, .org for organizations, and so on. Generally, the top-level domain is divided into two types:
Generic top-level domains (gTLD) – All domains that are not associated with any country are known as gTLD and work under the ICANN’s policies. For example, .com, .org, .net and others.
Country-code top-level domains (ccTLD) – All domain names associated with a country or geographical location are known as ccTLD and consist out of two letters like the US for the United States and NL for the Netherlands.
