Big problem – unlimited number /part/n/ page parts

Hi All.

I have a website, http://www.stelliollc.com/ where a static page is my home page.

That works great, now the problem.

I can do ENDLESS # of pages with this:

http://www[dot]stelliollc[dot]com/page/10/
http://www[dot]stelliollc[dot]com/page/100/
http://www[dot]stelliollc[dot]com/page/1000/

All those URL’s load just fine! Why? It is causing horrible duplicate content issues.

I made the URL not valid as I dont want google crawling this page and following those links and then indexing those also for duplicate content!

How do I fix this?
