I'm looking for opnions/experiences about links from the same Class C IP. When does a dampening effect kick in. Let's kick around these scenarios:

BASELINE: One inbound link from a high Page Rank page - Optimial?

MULTIPLE LINKS ON SAME PAGE TO A SINGLE URL: Three inbound links with different anchor text from a single page to a single URL. (Do the second or third link really matter? Will the different anchor text count for anything?)

MULTIPLE LINKS ON SAME PAGE TO MULTIPLE URL'S ON A SINGLE SITE: Three links with different anchor text from a single page to different URL's on a site. (Deep linking is always good but does any link above one have any increased effect?)

MULTIPLE LINKS ON DIFFERENT WEB PAGES IN A SITE TO A SINGLE URL: Say you buy a sidewide text link with the same anchor text pointing to a single URL. Google probably recognizes this but I've seen discussion that Yahoo/MSN still haven't been able to figure this out and you end up getting credit for it. Is there any benefit to links > 1 from a single domain?

MULTIPLE LINKS ON DIFFERENT WEB PAGES WITH DIFFERENT ANCHOR TEXT TO DIFFERENT URL'S ON A SITE: Let's say you have ten pages on a domain where you can get different anchor text pointing to ten different pages on another domain. Does this raise flags? What if it's a hundred? I would imagine a thousand or so would start to raise eyebrows in Mountain View.

Now let's add multiple sites on a single IP.

THREE UNIQUE DOMAINS, SAME IP, NOT CROSS LINKED, WITH SINGLE LINKS TO A SINGLE URL ON A DIFFERENT CLASS C IP ADDRESS: Three domains on 123.123.123.123 that are redwidgets.com, bluethingie.com, and greenwhatchamacallit.com that do not cross link giving a single link to purpleblahblah.com which exists on 234.234.234.234. I don't think this raises red flags. Or does it?

ONE THOUSAND DOMAINS, SINGLE IP, NOT CROSS LINKED, WITH SINGLE LINKS TO A SINGLE URL ON A DIFFERENT CLASS C IP ADDRESS: I think this raises flags.

Now let's make it the same Class C IP range.

FIVE DOMAINS ON THE SAME CLASS C RANGE, NOT CROSS LINKED, WITH FIVE LINKS FROM EACH DOMAIN POINTING TO A SINGLE URL: So let's say that redwidgets.com, bluethingie.com, etc are on different IP's but are on the same subnet so it is the same Class C address, 123.123.123.x x x. And you get multiple links from these sites to a single URL or multiple URL's within the same site. Are flags raised here?

ONE THOUSAND DOMAINS ON THE SAME CLASS C RANGE, NOT CROSS LINKED, WITH MUTLIPLE LINKS FROM EACH DOMAIN POINTING TO MULTIPLE URL'S ON THE SAME DOMAIN: You can see where I'm going on this.

Let's discuss.

(BTW, I guess x x x with no spaces in between gets filtered out to be #*$! - lol)
