[Dev-C++] C++ Sockets

[angel d. <sci...@ho...>]

 
Hello....
 
I created a simple Sockets server that's hosting on port 80.
I created an account for DynDNS and I created dynamically DNS with my computer IP address.
 
When I test my server using 192.168.1.102 it works perfectly however when I test my server with 
my computer IP (same as http://whatsmyip.org/ which is the same as DynDNS DNS) it doesn't work.
 
When I try to create a socket with my computer Ip (http://whatsmyip.org/), it doesn't even work. It give me this error:
 
WSAEADDRNOTAVAIL10049
 

Cannot assign requested address. 

The requested address is not valid in its context. This normally results from an attempt to bind to an address that is not valid for the local computer. This can also result from connect, sendto, WSAConnect, WSAJoinLeaf, or WSASendTo when the remote address or port is not valid for a remote computer (for example, address or port 0).
Can someone help me on how can I host my C++ server using my own computer ip (http://whatsmyip.org/).?

Thanks for the reply......I'll search for (tracert) on google and see what's that about... First time I hear it. Yes, I am connected through a router (Linksys) and I already set it up with DynDNS so that whenever I type my DNS the router looks for my computer (only my real IP Address).  Also, I have this program called (DynDNS updater) that I downloaded from DynDNS website which automatically sets my dynamic IP (EX: 192.167.1.102) with my DNS. My question is: is it possible to create a Socket Server using my real Computer IP Address (http://whatsmyip.org/)?or do I have to set my router to look for my dynamic IP (192.167.1.102) whenever I request my DNS or Real IP Address?

If you are accessing the Internet through a router, it is probably
doing NAT/PAT. The 192.168.1.102 address is a private address, that
is, it cannot be assigned to any interface on the public Internet. In
contrast, the address returned by whatsmyip is the IP address of the
public interface of your router.

Best regards,

Fernando
