Yes, but in the case of onion routing, the IP address is masked by layers of the onion.<p>It&#x27;s understandable that Layer 3 knows Layer 2, that Layer 2 knows Layer 1 and that Layer 1 knows the originator.<p>But Layer 2, 3 and the website should not know Layer 1 by design. Defeating this is akin, IMHO, to circumventing a lock by photographing the key that you don&#x27;t own.
