Please try with this

<%

string strHostName = System.Net.Dns.GetHostName();
string clientIPAddress = System.Net.Dns.GetHostAddresses(strHostName).GetValue(1).ToString();
Response.Write(clientIPAddress);

%>

Thanks

You can use : 

HttpContext.Current.Request.ServerVariables.Get("REMOTE_ADDR");

Following are the ways. to get IP Address

1. HttpContext.Current.Request.ServerVariables.Get("REMOTE_ADDR");

2. Context.Request.ServerVariables ["REMOTE_ADDR"].ToString();

3. Request.UserHostAddress.ToString();

4. string myHost = System.Net.Dns.GetHostName();

HttpContext.Current.Request.UserHostAddress.ToString()

Request.ServerVariables["REMOTE_ADDR"].ToString()

both are the same.

If you are trying to get your own external IP Address, please see http://externalip.codeplex.com/

Try this

          Request.ServerVariables["REMOTE_ADDR"]

is there any other way to get the ip address which really work...please help me out....thnks in advance...

This worked for me.

Thank you so much.  

simply if you run the code on a class or the global you wont be able to get the remote IP address

just run this code on any code behind page and you'll get the remote user IP

 Request.UserHostName

you can try my URL http://www.jamalq.com/testing.aspx

if you need the IP on the class just pass it through string

 hope this help

hmmm nice very niceeeee
