How to get Client Machine Name in asp.net using C# ?

Muhammad Mohsan

By using

Request.UserHostName also returns IP Address instead of returning Name while

Request.UserHostAddress working fine for IP Address.

Please guide me how can I get Client machine in asp.net application using C# or any other mechanism used for this purpose ?

string PCName = Dns.GetHostEntry(Request.ServerVariables["REMOTE_ADDR"]).HostName;

Hi guys.
Thanks to all of you for replying posts.

string PCName = Dns.GetHostEntry(Request.ServerVariables["REMOTE_ADDR"]).HostName;
Dns.GetHostEntry(Request.ServerVariables["REMOTE_HOST"]).HostName;
both are working fine on same Network and on desktop Browser but when logging from mobile browser it gives SocketException. No Such host is known

Let us know how to fix this exception.

As far as I remember, in order to get:
- Request.ServerVariables["REMOTE_ADDR"]
- Request.ServerVariables["REMOTE_HOST"]
- Request.ServerVariables["REMOTE_USER"]
you have to enable Reverse DNS Lookup for you IIS.
p.s. atm I'm not able to test it myself, so I'm not quite sure if this will solve ur problem
Thanks stackoverflow.com team for your efforts.

Did you try the following:

Request.ServerVariables("REMOTE_HOST")

Hi,

Try this code :
System.Net.IPHostEntry ipList;
ipList = System.Net.Dns.GetHostByAddress(Request.ServerVariables["REMOTE_HOST"].ToString());
Response.Write(ipList.HostName.ToString());
