Aug 23, 2014 at 14:39 comment added Lightness Races in Orbit Complete except you stop at "only if it is addressed to you" and don't describe what form this takes (i.e. port forwarding), which is bad because your answer quite correctly begins by enforcing the point that, to the outside, the mail is never directly addressed to you.

Aug 22, 2014 at 14:24 comment added Taejang @Thomas Routers almost always use the internal IP address inside a network. That said, routers can be configured to use MAC addresses, names that correspond to a DNS list stored on a server, or even other ids manually stored in the router's config. Such methods are just about exclusive to businesses, universities, and other large networks. Routers can also be configured to route things to other routers to divide the work in large networks; this is usually done with router IP addresses (which are internal).
Aug 22, 2014 at 14:15 comment added Taejang @Sarge I've never heard the analogy before. What differences are there between my version and what you use for students? I might nab better parts from your version for future use.
Aug 22, 2014 at 7:30 comment added Thomas so in a packet sent on the internet, does the router encapsulate the internal ip address (or another internal id) ?
Aug 21, 2014 at 22:32 comment added Sarge We use almost this same house analogy where I work to teach networking basics to some of our students that don't quite get how routing works. Works every time.
