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 http://12.34.56.78 confuse you.
 12.34.56.78 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.
