It is possible, but it is also quite easy to hide your activity from such inquiries. For example, lets check Address 15VjRaDX9zpbA8LVnbrCAFzrVzN7ixHNsC:
We can see that most often it appears in the USA, with a dominant IP being 188.8.131.52 . If we check that IP with another tool, we can see that it was owned by Linode. And indeed, this is the address of the Bitcoin Faucet, that used to be hosted on Linode.
However, if you were to say, start your Bitcoin with -connect flag and specify an IP that you know will be running Bitcoin most of the time and not be malicious (such as a trusted pool, the Faucet, or the like), your transactions will appear to come from that IP. Switch the IPs every now and then, and you have a total control of what other people can see the origins as.
So yes, it is possible to infer some information about what IP owns which Bitcoin Address, but it is also possible to hide such data if there are any trusted nodes on the Bitcoin network.
