To preempt nitpicking on the example I gave (by someone
who may read the mail archive months later), I should
clarify it's understood that not all URIs come with
schemes, which are for _indicating_ the protocols to
access the resources.  That is, we know URLs come
with schemes; URNs don't.

Subject: RE: URI's

Thought the following portion of a previous message of mine
to Roger would +1 to Hugo's and help close out the issue.

 The two differ in purpose and syntax, among other things.
 Don't let URIs like confuse you. is an IP address.  It's a part of a URI, but not
 a URI, which comes with (the http) scheme, separators, ...
 IP addresses are for identifying network nodes on the Internet.
 URIs are for identifying resources on (or even off) the web.
 I can go on and on, like trying to differentiate apple from orange.
 BTW, The reference to NAT only clouds your question.  
 It's irrelevant to differentiating IPaddr from URI.
