Getting Client IP address in WCF with wsDualHttpBinding

I am using the following code in my service

public class HeartBeat : IHeartBeat
{
    public string GetData()
    {
        OperationContext context = OperationContext.Current;
        MessageProperties prop = context.IncomingMessageProperties;
        RemoteEndpointMessageProperty endpoint =
            prop[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
        string ip = endpoint.Address;

        return "IP address is: " + ip;
    }
}

I noticed that if my web config is:

<protocolMapping>
  <add binding="basicHttpBinding" scheme="http" />
</protocolMapping>

I can get the IP address successfully. However, if i use dual http binding like this:

<protocolMapping>
  <add binding="wsDualHttpBinding" scheme="http" />
</protocolMapping>

I am getting a null return. Is there any other way to get IP address of client in wsDualHttpBinding? Thank you in advance

Finally figured it out using @Neel

public class HeartBeat : IHeartBeat
{
    public string GetData()
    {
        OperationContext context = OperationContext.Current;
        MessageProperties prop = context.IncomingMessageProperties;
        RemoteEndpointMessageProperty endpoint =
            prop[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
        string ip = endpoint.Address;

        EndpointAddress test = OperationContext.Current.Channel.RemoteAddress;
        IPHostEntry ipHostEntry = Dns.GetHostEntry(System.ServiceModel.OperationContext.Current.Channel.RemoteAddress.Uri.Host);

        foreach (IPAddress ip2 in ipHostEntry.AddressList)
        {
            if (ip2.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
            {
                //System.Diagnostics.Debug.WriteLine("LocalIPadress: " + ip);
                return ip2.ToString();
            }
        }

        return "IP address is: " +  System.ServiceModel.OperationContext.Current.Channel.RemoteAddress.Uri.Host;
    }
}

This happens because RemoteEndpointMessageProperty.Address property appears empty in case of wsDualHttpBinding.

The RemoteEndpointMessageProperty uses the HttpApplication.Request.UserHostAddress to return the IP. however, the HttpContext is not available with WSDualHttpBinding, causing a "Request is not available in the context" exception.

You can try to access host property like below for dual channel.

if (string.IsNullOrEmpty(endpoint.Address))
{
    string clientIpOrName = System.ServiceModel.OperationContext.Current.Channel.RemoteAddress.Uri.Host;
}
