They seems to be registered at "Directi Web Technology Pvt. Ltd" which is a domain register.

It also doesn't say it is the top sites in the world as in visited. It just says that these are the sites being linked to by other sites (in the root dir).

Feels to me that this company set up 1.6 million websites all having links to these URLs. Because they all have the same amount of websites linking to them.

As for the reason I have not the slightest idea.
