Hello all,

I have used VS2010 on windows 7 64bit machine. I can get host name on 32bit machine and working fine. But I got error as "No such Host is known" when using 64bit machine.
I was tryed all these 3 ServerVariables but still i got error.

C#

Request.ServerVariables["REMOTE_ADDR"]
Request.ServerVariables["REMOTE_HOST"]
Request.ServerVariables["REMOTE_USER"]

My code is:

C#

string hName = "";
System.Net.IPHostEntry host = new System.Net.IPHostEntry();
host = System.Net.Dns.GetHostEntry(HttpContext.Current.Request.ServerVariables["REMOTE_HOST"]);

if (host.HostName.Contains("."))
{
string[] sSplit = host.HostName.Split('.');
hName = sSplit[0].ToString();
}
else
{
hName = host.HostName.ToString();
}

It has nothing to do with the bitness of the machine. It has everything to do with whether the remote machine is registered in a DNS accessible by the server or not. Apparently, your 64-bit machine is not.
