Facts about Domain Name
When DNS was first implemented in 1980, it originally defined only 6 original Top Level Domains that were .com, .edu, .mil, .net, .org and .gov while there are more than 700 TLDs today on the internet. The wide expansion for domain names only happened post 2011 with the basic aim of better classification of the web sites, based on their purpose.
Currently, there are more than 100 million domains that are registered under .com solely.
