    Exclamation What is my really real IP ?

    Hi, there

    I want to know what is my real ip
    my computer is one of a group on a network Group

    so If I want to know my ip >> simple program i can make with a programming language will tell me that : 10.0.0.4

    ok.. now If I open any website that shows me my ip >> it gives me something like this : 82.209.158.133
    I think that this IP is the router's ...

    Now, If I want to contact my PC with a computer out of this NETWork Group with a server program installed on my pc and client Program on the outer computer... the client prog needs an ip and a port that is prepared before .... but

    WHAT IP CAN I GIVE TO THE CLIENT PROGRAM ? 10.0.0.4 OR 82.209.158.133 OR ..... what ?
    SO, What is my really real IP ???

    and ... thanks very much

    Thank you brain_damage for ur reply
    but... but i know that this is my real ip...

    I will illustrate my question :

    Let's suppose that their is a cafe shop that have some computers.
    If I want to see IPs of Computers, I will find them : ( imagine ip / real ip ) :

    computer1 : ( 10.0.0.4 / 82.209.158.133 )
    computer2 : ( 10.0.0.5 / 82.209.158.133 )
    computer3 : ( 10.0.0.6 / 82.209.158.133 )
    computer4 : ( 10.0.0.7 / 82.209.158.133 )
    computer5 : ( 10.0.0.8 / 82.209.158.133 )
    computer6 : ( 10.0.0.9 / 82.209.158.133 )
    computer7 : ( 10.0.0.10 / 82.209.158.133 )

    So, I noticed that all computers have the same real ip (82.209.158.133)

    and Let's suppose that their is a Server Program installed on (computer1) in this cafe shop
    And now i want to contact this (computer1) by a client program but out of this cafe shop.

    I have tried to contact it's ip : 10.0.0.4 and also 82.209.158.133 but... their is no connection in the two times.

    becase ( i think ) :
    10.0.0.4 : is not a real ip.
    82.209.158.133 : is the ip of router... so if i request connection with : (82.209.158.133, port: ##) it doesn't know which (computer#) i want to contact ( 10.0.0.4 or 10.0.0.5 or .... )

    This is the Problem.

    Hey!

    I like the part "Let's say there is that computer in the internet cafe"... on which you installed a backdoor and you wanna connect to using some trojan which most likely has been already detected and removed by their antivirus software, but even if... :

    Let's clarify that a bit:
    - The imaginary IP is your local area network IP
    - The real IP is the global IP

    Let's say you have an internet connection hooked up to the router.
    There is 10 computers connected to the router to form LAN.
    Router acts as a computer that allows all the LAN computers to see
    each other and use the internet by assigning the local IPs to them (the "imaginary" ones).
    Whenever any of the computers wants to use the internet it will connect through the router to the modem and then to the desired website/destination. And the "real" IP which is global is the MODEM's IP. Because all of the computers on the network connect to the internet through the same device (modem) then they [although different local ("imaginary") IP] will have the same global [("real") IP]

    I hope it is clear enough ;]

    In order for the computers to be visible from the internet you have to change some of the settings on the router (open the specific ports your program is using), but for that you need to refer to the router's manual!

    Good luck!
