Page works for me. But it gives you 22.214.171.124. Just tested it. (Mine is 126.96.36.199 no content, so why not).
Thought I’d save you a much longer download than 2.x. The bit above the button gives a thin hint “A newer version of Daz Studio is available.”
I think you’re back to the book idea.
A lot of people say the book is a great deal, on the other hand, you’ve been here since 2003, and might have most of the stuff, on the other other hand, it’s cheap.
