Get The Public IP Address Of The User Who Is Visiting My Website

I tried this below code. But it returned me ::1
string IPAddress = string.Empty;
string SearchName = string.Empty;
String strHostName = System.Web.HttpContext.Current.Request.UserHostAddress.ToString();
IPAddress = System.Net.Dns.GetHostAddresses(strHostName).GetValue(0).ToString();
I expect output should be Something like : (358.89.48.188)
So I'm looking forward for anyone who could help me out.
(By getting this I will get the location and pass it to Session,So my Controller and action reacts based on the client location)

try this...
public string GetIpAddress()
{
var ipAddress=Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if(string.IsNullOrEmpty(ipAddress))
{
return Request.ServerVariables["REMOTE_ADDR"];
}
return ipAddress;
}

How to Change Public IP Address in C#

I am creating a C# winform application, in which I want to change the Public IP Address, NOT the IPv4 Address like (Hotspot-Shield, ZenMate, OpenVPN, and others do).
I have checked the following links but didn't find enough help, so I am posting this question:
How can you change Network settings (IP Address, DNS, WINS, Host Name) with code in C#
Changing IP address in C#
I write the same code as in the answer of 1st link and also used the libraries but when I check my IP address through google.com it remains the same. I don't know the socket programming.
Here is my code:
namespace WindowsFormsApplication1
{
class ChangeIP
{
public void SetIP(string ipAddress, string subnetMask, string gateway)
{
using (var networkConfigMng = new ManagementClass("Win32_NetworkAdapterConfiguration"))
{
using (var networkConfigs = networkConfigMng.GetInstances())
{
foreach (var managementObject in networkConfigs.Cast<ManagementObject>().Where(managementObject => (bool)managementObject["IPEnabled"]))
{
using (var newIP = managementObject.GetMethodParameters("EnableStatic"))
{
// Set new IP address and subnet if needed
if ((!String.IsNullOrEmpty(ipAddress)) || (!String.IsNullOrEmpty(subnetMask)))
{
if (!String.IsNullOrEmpty(ipAddress))
{
newIP["IPAddress"] = new[] { ipAddress };
}
if (!String.IsNullOrEmpty(subnetMask))
{
newIP["SubnetMask"] = new[] { subnetMask };
}
managementObject.InvokeMethod("EnableStatic", newIP, null);
}
// Set mew gateway if needed
if (!String.IsNullOrEmpty(gateway))
{
using (var newGateway = managementObject.GetMethodParameters("SetGateways"))
{
newGateway["DefaultIPGateway"] = new[] { gateway };
newGateway["GatewayCostMetric"] = new[] { 1 };
managementObject.InvokeMethod("SetGateways", newGateway, null);
}
}
}
}
}
}
}
/// <summary>
/// Set's the DNS Server of the local machine
/// </summary>
/// <param name="nic">NIC address</param>
/// <param name="dnsServers">Comma seperated list of DNS server addresses</param>
/// <remarks>Requires a reference to the System.Management namespace</remarks>
public void SetNameservers(string nic, string dnsServers)
{
using (var networkConfigMng = new ManagementClass("Win32_NetworkAdapterConfiguration"))
{
using (var networkConfigs = networkConfigMng.GetInstances())
{
foreach (var managementObject in networkConfigs.Cast<ManagementObject>().Where(objMO => (bool)objMO["IPEnabled"] && objMO["Caption"].Equals(nic)))
{
using (var newDNS = managementObject.GetMethodParameters("SetDNSServerSearchOrder"))
{
newDNS["DNSServerSearchOrder"] = dnsServers.Split(',');
managementObject.InvokeMethod("SetDNSServerSearchOrder", newDNS, null);
}
}
}
}
}
}
}
And Here is how I am calling those methods:
{
static string local_ip;
string public_ip;
public static string GetLocalIPAddress() //Method For Getting Local Machine IP
{
var host = Dns.GetHostEntry(Dns.GetHostName());
foreach (var ip in host.AddressList)
{
if (ip.AddressFamily == AddressFamily.InterNetwork)
{
return ip.ToString();
}
}
throw new Exception("Local IP Address Not Found!");
}
// Mehod End
local_ip = GetLocalIPAddress();
ChangeIP ip = new ChangeIP();
ip.SetIP(local_ip, null, null); // Calling Method
var getNIC = NetworkInterface.GetAllNetworkInterfaces();
NetworkInterface[] NI = NetworkInterface.GetAllNetworkInterfaces();
string nic = string.Empty;
string dnsServer = string.Empty;
foreach(var r in getNIC)
{
nic = r.Name;
}
foreach(NetworkInterface ninter in NI)
{
if(ninter.OperationalStatus == OperationalStatus.Up)
{
IPInterfaceProperties ipProperties = ninter.GetIPProperties();
IPAddressCollection dnsAddresses = ipProperties.DnsAddresses;
foreach(IPAddress dnsAdrs in dnsAddresses)
{
dnsServer = dnsAdrs.ToString();
}
}
}
ip.SetNameservers(nic, dnsServer); // Calling Method
public_ip = new WebClient().DownloadString("http://icanhazip.com");
}

How you've described your question is not how the internet (is supposed to) work(s).
Windows doesn't let you write raw IP packets, for this you need to use a TAP/TUN driver. But although you send out packets spoofing the source IP address, the internet between you and the destination won't return the route.
If you're operating behind a block of IP addresses, and only want to spoof another in that block, the return address will get back to your local router, but still won't necessary route back to you.
Unless you use TAP/TUN, there's no other way to steal someone else's Public IP address, excluding other network security vulnerability exploitations which are beyond the scope of this forum.
And even with TAP/TUN you're very limited in what you can achieve over spoofed IP packets in one direction. In fact, ISPs may filter out spoofed IP addresses.

Converting IPAddress[] to string

I've got a server application which I'm trying to automatically set the IP address to, taken from the machine's dynamically allocated IP address. So far I've got this to get the IPv4 but it's returned as type IPAddress[] which I have some trouble converting to a string[] so my HttpListener can use it. Any hint to how I can convert it? Or am I going about this the wrong way?
This is what I'm using to get the IP address:
class Program
{
static void Main(string[] args)
{
string name = (args.Length < 1) ? Dns.GetHostName() : args[0];
try
{
IPAddress[] addrs = Array.FindAll(Dns.GetHostEntry(string.Empty).AddressList,
a => a.AddressFamily == AddressFamily.InterNetwork);
Console.WriteLine("Your IP address is: ");
foreach (IPAddress addr in addrs)
Console.WriteLine("{0} {1}", name, addr);
//Here I'm trying to convert the IPAddress[] into a string[] to use in my listener
string str = addrs.ToString();
string[] ipString = { str };
Response.Listener(ipString);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
//current way of setting the IP address - not optimal
string[] ipstring = new string[1] {"10.10.180.11:8080"};
Response.Listener(ipstring);
}
}
And the listener for good times sake:
public static void Listener(string[] prefixes)
{
if (!HttpListener.IsSupported)
{
Console.WriteLine("Windows XP SP2 or Server 2003 is required to use the HttpListener class.");
return;
}
// URI prefixes are required,
// for example "http://contoso.com:8080/index/".
if (prefixes == null || prefixes.Length == 0)
throw new ArgumentException("prefixes");
// Create a listener.
HttpListener listener = new HttpListener();
// Add the prefixes.
foreach (string s in prefixes)
{
listener.Prefixes.Add("http://" + s + "/");
}
listener.Start();

This should do the trick.
string[] ips = addresses.Select(ip => ip.ToString()).ToArray();
Make sure you have a using statement for System.Linq

You are trying to convert an IPAdress's array like one IPAdress.
You can use LINQ to convert each IPAdress, then you can make the String's array :
String[] strAddrs = (from cad in addrs select cad.ToString()).ToArray();
Don't forget : using System.Linq;

If you have an IPAddress object, you can get the string representation like this:
v4:
validIP4.MapToIPv4().ToString();
v6:
validIP4.MapToIPv6().ToString();

spamassassin check score C# code

Is there a way to check the score in an ASP.Net application? A class or something similar for .Net? How about other Spam Filters out there.
--Edited
I am looking for a way to check the spam score of the email messages in C#.

Here is my super simplified "just check the score" code for connecting to a running Spam Assassin email check from C# which I wrote for http://elasticemail.com. Just setup SA to run on a server and set the access permissions.
Then you can use this code to call it:
public class SimpleSpamAssassin
{
public class RuleResult
{
public double Score = 0;
public string Rule = "";
public string Description = "";
public RuleResult() { }
public RuleResult(string line)
{
Score = double.Parse(line.Substring(0, line.IndexOf(" ")).Trim());
line = line.Substring(line.IndexOf(" ") + 1);
Rule = line.Substring(0, 23).Trim();
Description = line.Substring(23).Trim();
}
}
public static List<RuleResult> GetReport(string serverIP, string message)
{
string command = "REPORT";
StringBuilder sb = new StringBuilder();
sb.AppendFormat("{0} SPAMC/1.2\r\n", command);
sb.AppendFormat("Content-Length: {0}\r\n\r\n", message.Length);
sb.AppendFormat(message);
byte[] messageBuffer = Encoding.ASCII.GetBytes(sb.ToString());
using (Socket spamAssassinSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp))
{
spamAssassinSocket.Connect(serverIP, 783);
spamAssassinSocket.Send(messageBuffer);
spamAssassinSocket.Shutdown(SocketShutdown.Send);
int received;
string receivedMessage = string.Empty;
do
{
byte[] receiveBuffer = new byte[1024];
received = spamAssassinSocket.Receive(receiveBuffer);
receivedMessage += Encoding.ASCII.GetString(receiveBuffer, 0, received);
}
while (received > 0);
spamAssassinSocket.Shutdown(SocketShutdown.Both);
return ParseResponse(receivedMessage);
}
}
private static List<RuleResult> ParseResponse(string receivedMessage)
{
//merge line endings
receivedMessage = receivedMessage.Replace("\r\n", "\n");
receivedMessage = receivedMessage.Replace("\r", "\n");
string[] lines = receivedMessage.Split('\n');
List<RuleResult> results = new List<RuleResult>();
bool inReport = false;
foreach (string line in lines)
{
if (inReport)
{
try
{
results.Add(new RuleResult(line.Trim()));
}
catch
{
//past the end of the report
}
}
if (line.StartsWith("---"))
inReport = true;
}
return results;
}
}
Usage is quite easy:
List<RuleResult> spamCheckResult = SimpleSpamAssassin.GetReport(IP OF SA Server, FULL Email including headers);
It will return the list of spam check rules you hit and the resulting score impact.

I am not exactly sure if that's what you are searching for, but there is a C# wrapper that simplifies the communication with a SpamAssassin server on Code Project:
A C# Wrapper for the SpamAssassin Protocol
Hope that helps!
