Particularly with the java.net APIs; you wrap your hostname in an InetAddress object and then pass it to a socket without really needing to know that it's been resolved to an IP address underneath. And issues with NAT only arise if you are writing a server - and even then you don't need to *understand* NAT; the knowledge that servers shouldn't be "behind firewalls" is enough for most people. I am more concerned about server authors knowing how to implement an authentication and authorisation system than about them understanding NAT... > And you can't do > significant Web work without understanding a fair bit about HTTP: how > addressing works, how to respond to events, etc. Hmmm... you need to know HTML to make Web stuff, but not HTTP; I know people who are writing server-side scripts with no real understanding of HTTP. The advanced ones know that <? header ("Location: http://www.foo.com/") ?> magically causes a redirect, but apart from that it 'just works' that the browser's request gets to their script. > > Paul Prescod > ABS -- A city is like a large, complex, rabbit - ARP
