Domain Numbers
The World Wide Web really is exceptionally wide. There are diverse methods of measuring and tracking domains, yet still it’s a tricky question to answer how many domains there actually are.
By reviewing the available numbers, we can get a good sense of the number of domains and the most popular among them.
Types of Domains
Domains are defined by their roots, also known as domain extensions. There are 1,589 currently registered domain root types, according to the database of IANA.
These include Top-Level Domains (TLD) also known as Generic Top-Level Domains (gTLD). They are the most generic category and include all types of domains. The second category is the Country-Code Top-Level Domains (ccTLD) which are defined by their country of registration. The third category is the New Generic Top-Level Domains (ngTLD). They are newly registered in the database. The fourth category is Geo New Generic Top-Level Domains (Geo ngTLD) which are denoting geographical, geopolitical, ethnic, or cultural representation.
How Many Domains Exist in Total? 
In total, there are currently 367.3 million domain names registered. Though this seems like a comparatively high number, domain name registrations have decreased year-over-year. Compared to 2017, there were over 600 million fewer websites registered by 2021.
