What are the major the types of generic top-level domain available?
Unrestricted gTLD – this is a series of domains that are offered and are available for registrations by every individual or organization. They can be put into any use by the owners once they have been assigned. The most prominent of these domains are com, net, org, and info. Initially, info was the only one that was truly unrestricted. However, over time and especially due to poor reinforcement of the laws, the rest became unrestricted as well.
Sponsored gTLD – these are domains that are derived domains that are based on theme concepts, which are often proposed by private agencies or such other organizations. These organizations establish and enforce the rules.
The others that fall into this category include: Geographic gTLD and the New top-level domains that started off as late as the year 2008.
