When i checked my connection from the website and from the command windows, it seems connection is established properly and i have started using the ipv6 address given to my use. Only problem is when i check my ip address from websites such as whatismyip.com, it still shows my ipv4 address. Could somebody please explain this to me? Also during the installing of aiccu i have an error-ish warning in command windows. it was written as "netsh firewall" command is out of use. instead of it, use "netsh advfirewall firewall". do i need/have to do something about it. i am windows 7 user btw. Thanks for the replies.
