Domain suffixes, also known as top-level domains (TLDs), are the last part of a domain name, following the final dot (e.g., .com, .org, .edu). These domain suffixes are controlled and managed by various organizations known as domain name registries.
The most common top-level domains are the generic top-level domains (gTLDs) such as .com, .org, .net, .info, .biz and .gov. These gTLDs are available to anyone who wants to register a domain name.
There are also country code top-level domains (ccTLDs), which are two letters long and are used to identify a specific country or territory, such as .fr for France or .cn for China.
The Internet Assigned Numbers Authority (IANA) is responsible for the allocation of top-level domains. They are also responsible for maintaining a list of all top-level domains, both generic and country code.
In summary, domain suffixes (TLDs) are the last part of a domain name that follows the final dot (.) and they are controlled and managed by various organizations called domain name registries. They are divided into generic top-level domains (gTLDs) and country code top-level domains (ccTLDs) and are managed by the Internet Assigned Numbers Authority (IANA)
