Welcome to the Q&A Forum

Google would prefer in most cases not to index search results. What we find best is a method called Tag Seeding, where essentially you are linking to a set of known tag pages that help Google find the relevant categorical results. This helps prevent Google from finding an unending number of pages while, at the same time, allowing you to expose users to your content in an organized fashion.

Thanx for the good response Harald and Robert. I agree. Logically I know Google ranks domain names, not IPs. But technically I am sure they use that data.

Answered. Thanx mate.

Thank you very much, did not know that list existed.
