It is entirely possible for multiple websites to have the same ip address. In this instance they would all be running on the same server, it all works by using the host headers sent by your browser (or virtual hosts in the apache world). I don't believe they are duplicating ip addresses, if they did the results would be totally unpredictable eg you could visit one website but get another depending on which server responded first etc.
Apologies if you are already aware and I misunderstood all the posts, but I thought it best to point that out before complaints were raised.

I was thinking the exact same thing. This is very common and perfectly legitimate practice. Hosting companies could not work without host header resolution, as they would run out of IP Addresses in no time flat. Unless the whole world moves over to IPv6 it would be impossible for all websites to have unique IP addresses.

They could be on separate servers, as they could be on a network behind the firewall. Something at firewall/router level would just be looking at the Host Header and routing it to the various different physical servers. But to the user/client - they all appear as one IP. This is all OK tho.
