Introduction

In my recent project I was told to keep  track of the IP address of all the visitors. Here I will show you how to get IP address of the client machine in csharp in asp.net.

There are many ways you can get the IP address of a client machine.

1. 

 string strClientIp=Request.UserHostAddress();

2. 

string strDNS = Dns.GetHostName();
string strClientIP = HttpWorkerRequest.GetRemoteAddress().ToString();
 

3. If you are calling from web service use code below

string strClientIP = Context.Request.ServerVariables ["REMOTE_ADDR"] 

4. 

string host = Dns.GetHostName();
IPHostEntry ip = Dns.GetHostEntry(host);
string strClientIP = ip.AddressList[0].ToString());

Enjoy coding.........
