It's true that this doesn't list all the websites that are registered, nor do all the domains lead to a working website. However, I think that most of the invalid websites are not caused by NS entries. As for the Zone File Access Agreement, it prohibits uses that allow the access of a significant portion of the data. An immense amount of time would have to be spent scraping data to get any portion that could be considered significant.

Also, there are alternative, publicly accessible ways to get most of this public zone file data now, so I am not sure that restriction in the access agreement is anything more than an historical artifact at this point.

You could use publicly available scan data for ports 80 and 443 to pare down the list of "websites".

The goal of exposing the non-popular web is worthwhile.

Thanks, I appreciate the feedback!

You could port scan the entire IPV4 address space(minus all reserved addresses), send a GET request to everyone that responds, filter for valid HTML. It would take no more than 5 hours on a shitty PC, a lot less if you get a small aws instance.

Most non-major sites are on shared hosting. Without a host name, you won't get anything useful unfortunately.

Most major site are on shared hosting. (Sadly)
