ASP.NET : how to get ip address using csharp(c#)


How to get a client's ip address with ASP.NET :
                                         Internet protocol is a communication between the nodes. Internet protocol, which is used to track a system host and used address the location. If we need to identify the user who are all accessing our website and store the Internet protocol address in our database.

                                Fetch a client's Internet protocol address as soon as he access our web site in Some of them may use a proxy Internet protocol address. But we can get their Internet protocol address with this simple code.

//Add the Namespace
using System.Net;
//Get Visitor IP address method
public string GetVisitorIpAddress()
string stringIpAddress;
stringIpAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (stringIpAddress == null) //may be the HTTP_X_FORWARDED_FOR is null
stringIpAddress = Request.ServerVariables["REMOTE_ADDR"];//we can use REMOTE_ADDR
return "Your ip is "+stringIpAddress;
//Get Lan Connected IP address method
public string GetLanIPAddress()
//Get the Host Name
string stringHostName = Dns.GetHostName();
//Get The Ip Host Entry
IPHostEntry ipHostEntries = Dns.GetHostEntry(stringHostName);
//Get The Ip Address From The Ip Host Entry Address List
IPAddress[] arrIpAddress = ipHostEntries.AddressList;
return arrIpAddress[arrIpAddress.Length - 1].ToString();
//Get The Visitor Ip Address
string strVisitorIpAddress = GetVisitorIpAddress();

//Get The Lan Ip Address
string strLanIpAddress = GetLanIPAddress();
