    Okay we all know unique ips (especially c-class) are good.

    And google devalued sub-domains a while back, to approx directory level. i.e. they treat everything as one site.

    Now what about subdomains on different ips??

    I've an idea that will require thousands of domains, to generate thousands of "unique" sites. Obviously putting them all on the same ip, will get them tied together, but I really don't want to pay for thousands of domain names.

    Any idea folks?

    No point in putting tons of subdomains on tons of IPs. The fact that they're all under the same domain proves that they're all owned by the same person, and thus all backlinking between them (which I assume you're planning on doing) will be either deeply discounted, flat out ignored, or (worst case scenario) get your entire domain (and all subs) completely de-indexed.

    I'm about 99% sure that what I said is true. I invite anyone who knows otherwise to correct me if I'm wrong.

    My sentiments as well. If Google treats subs like separate sites, not sure what the value of having subdomains rather than separate IPs.
