I was with you until &quot;so that IP addresses finally can represent identity&quot;.<p>You don&#x27;t mean actual (personal&#x2F;account) identity, do you?  IP addresses represent a <i>location</i> for delivery and they definitely identify a network <i>interface</i>, but that&#x27;s the extent of goals for IP addressing.  Courts have supported this view and I <i>think</i> that&#x27;s a good thing.  Sorry if I read too much into what you said.  EDIT: spelling.
