Duplicate content - multiple sites hosted on same server with same IP address

[Jade]

We have three sites hosted on the same server with the same IP address. For SEO (to avoid duplicate content) reasons we need to redirect the IP address to the site - but there are three different sites. If we use the "rel canonical" code on the websites, these codes will be duplicates too, as the websites are mirrored versions of the sites with IP address, e.g. www.domainname.com/product-page and 23.34.45.99/product-page. What's the best ways to solve these duplicate content issues in this case?

Many thanks!

Its early for me and I haven't had enough coffee yet so I may be misreading things. Why do you have three sites on the same IP address with three separate mirrored WWW versions?

As far as I can see... No reason you can't use Rel=Canonical to fix that issue though. If the code is going to be the same because of how they are mirrored then you'll have one site canonical'd to the right version and the right one canonical'd to itself... which shouldn't cause any issues. Can't guarantee that it will work in every instance though. Canonicals are a suggestion not a directive. So the bots will try to respect your tag but if they feel it is incorrect, improper, deceptive, etc. they can always choose not to.
