The problem is these links won't be able to point at my main web site. For technical reasons, they will have to go to something like:
(where my main site would be: IANA — Example domains)
So the high PR links would point to that server1.example.com sub.
If I put a link or two on the bottom of these pages (the pages on the server1.example.com address) back to my main page(s), will the value of those links get passed through to my main site?
In other words:
A is a high PR site. A links to B and B links to C. Does C gain the "link juice" from A?
