How can I get my global IP address? I can see my global IP address via a site: www.whatismyipaddress.com

More Info: I have multi Lan card.

I use VPN.

What do you mean the IP you see when connected to VPN is "not correct"? It is. That is the IP you're showing the outside world at that moment. –  CodeCaster Mar 12 '13 at 7:55
    
Seen from the outside world: Your machine is behind a NATting device? –  alk Mar 12 '13 at 7:56
    
when without using vpn: my address is X.X.X.X, but using vpn: my address is changed with Y.Y.Y.Y –  bTagTiger Mar 12 '13 at 7:57

If you have more network interfaces, you have more IP addresses. Actual IP address for a connection is chosen primarily by the target:

If you connect to localhost, you'll probably be connected as 127.0.0.1.

If you connect to some host in your vpn, you'll have IP from your VPN interface.

If you connect to some host in the internet, you'll have IP address of the interface responsible for the internet connection.

The IP address you see on a website is influenced by what is the setting of the VPN: If all trafic is passed through that VPN then you have VPN Interface's address - that's obvious. Check your internet [explorer] setting, if there isn't any proxy set by VPN and check your routing tables when the VPN is connected and disconected. That will answer all your questions.

I've seen route print and I cannot find out ip address without using vpn. But I can find out main iterface mac-address. I think we can find out my main ip address via main interface mac address –  bTagTiger Mar 12 '13 at 9:23
