Google Page Rank: A Question About It

I have a question about google page rank, I have read different information on how google page rank is used, also I noticed one thing, to not use the same content on other websites, I mean to not have multiple sites on different domains or else google might ban you and stuff, but my site can be visited from different domains, subdomains.. I recently bought a domain, which I would like to use as my main domain, but what I mean is that google already has indexed me on different ways: it is accessible by subdomain.astahost.com, domain.be, domain.co.nr and now domain.net .. also different sites can be accessed like this: subdomain.astahost.com/mysite/ and mysite.subdomain.astahost.com etc.So what I ask is what to do ? to remove the content and point everything to the new domain as "Moved" or to use all the sites and don't worry about it ? Would like your opinion.

You just have to submit the new domain to google. Usually, this is done automatically by Google, or your domain/Hosting service. But it might take time for Google to come to it eventually. You could go ahead and submit it yourself to Google at Google Submit yourself to speed it up. I've done this twice and it can take anything from a couple of weeks to a month to get added into google's index.

You don't have to worry about the old domains. Google's crawler will eventually phase out non-existent pages from it's database.

No, I know how to get it on google and how it works, I am just worried about that all the links will work and will point to the same content, just the url will be different. :S

oh ... ok. Not too sure about that. But it should work right? As far as google is concerned, if a website address is unique, it should index whatever that's there at the address right? I think it'll work fine.

I think you don't have to worry about that. A lot of big sites have several mirrors, each mirror having the same content as the other ones, and a master site asking you to choose your mirror, or choose another one if the first one fails.
Of course none of us needs that because Xisto is never down, but people on other sites have several mirrors, all with the same content, just in case one server fails. And these sites have no problems being indexed by google.

Thank You for making me not worry, I once got banned from google two years ago by cheating a little, but now I don't want to be not indexed, because google is one of my main traffic.

Be careful, some providers are automatically flagged as spammers. So, simply being hosted by this provider and mentionning it's address at the end of your mail makes this mail automatically go to the "spam" folder and makes your site being unreachable from people using professionnal firewall having a list of "known spammers".
