   Tom Impelluso to All   
   some confusion about my IP address   
   09 May 09 10:53:05   
   
   From: impellus@attila.sdsu.edu   
      
   Please allow me to ask some naive questions...   
      
   I normally run network codes from my university (where there is no ISP   
   intermdiary - or is there?)   
      
   But from home, I have this intermediary of cox.net; and this confuses me.   
      
   And I feel like a child re-learing things as I try to do more from home.   
      
   At home, on  my PC, I type ipconfig.   
   And I get 192.168.1.104   
      
   So would imagine that that cannot be my IP address (but what is it?)   
   (And, what is it in the context of me working at school on a UNIX machine   
   and going to /etc/hosts and seeing each machine with an IP address?)   
      
   From home, when I go to whatismyip.com, I get: 68.167.43.161   
   However, ALL the laptops in my home have 68.167.43.161   
   So where is the unique number here?   
      
   I have logged into my router and THOUGHT I was accessing the port   
   forwarding calls properly.   
      
   But now I am not so sure...   
      
   So... In a nutshell:   
      
   1. What is it about my university that, when I run a code as a server and   
   decide it will accept connections on a a port above 6000 (socket, bind,   
   listen, accept, socket, connect)... done... over... easy... never had   
   a problem.   
      
   2. What is it  about cox that I have this intermediary... and how can I   
   find out what port is the one for my current laptop.   
      
   I can connect to my router and forward the ports...   
      
   But could someone please take the time to frame what is happening?   
      
   (I know my IP  cannot be 192.168.1.104 .... but what IS that number   
   specific for?  Cox?  Linksys (and only Linksys) routers?  all routers?   
      
   Confused...
