Backlink or not a backlink

[traian]

Does really a link from www.yoursite.com/abc.hmtl pointing to www.yoursite.com/def.html is a backlink?
When searching google with link:www.yoursite.com/abc.html it shows you "backlinks" from www.yousite.com/def.html. This means that G consider a link from within the same site a backlink? If so, why not all link pointing to a page are not considered backlinks when using link: command? Is there a trick to make google think that such links are backlinks?

Do this (http://www.google.com/search?num=100&hl=en&lr=&rls=GGGL%2CGGGL%3A2006-13%2CGGGL%3Aen&q=link%3Ahttp%3A%2F%2Fwww.hotelclub.net%2Fhotel.re servations&btnG=Search) query on google and you'll see what I mean.

What do you think?

Thanks

Those are internal links - not true backlinks. They are not weighted similarly. They come from the same IP address. Google understands that these links are not pointing from other sites and as a result they are not weighted as such.

This is my favorite link analysis tool (http://www.linkhounds.com/link-harvester/backlinks.php)

Type your URL in there.

It is not the IP that matters but the domain : a links from a different domain but hosted on the same IP will be seen as an external one.

it has been my experience that links from the same IP are devalued or at least carry less weight.

No?
