Today we’ve faced a weird problem.
While we are debugging noticed that we can not get the IPv4 address of the requester. Instead we were getting IPv6.
string userHostAddress = HttpContext.Current.Request.UserHostAddress;
This code returns “::1” instead of “127.0.0.1”.
After a little search this is about the Vista’s hosts file problem. And this is only a development issue for Vista systems.
Open your hosts file ( %WinDir%\System32\drivers\etc\hosts ) see the entry “::1 localhost”. Feel free to remove line or comment the line with #.
Happy codding…
