is there a way to capture a server's IP address in a web service

[dove11]

I have created a web service on our server. The client created an application to send us some information in a SOAP header. We process this information and return some values back to them. This is working fine, but we wanted to capture the client's server IP address when we record our logins. Using Request.UserHostAddress will capture the IP address from the client's computer, not from the their web server. Is this possible to do? Or would they need to pass it through a SOAP Header.

What environment are you in? In .NET you can use System.Net.XXXX to obtain the machines hostname and IP. If in C++ you can use the sockets API.

Hi Mike. Thanks for replying. I am using Microsoft Development Environment 2003 Version 7.1.3088, Microsoft .NET Framework 1.1 Version 1.1.4322 SP1, Microsoft Visual Basic .NET, ASP .NET. Marcy

using System.Net;

System.Net.IPHostEntry hostent = Dns.GetHostEntry("localhost");
foreach (IPAddress addr in hostent.AddressList)
{
Debug.WriteLine(String.Format("{0}:{1}", addr.Address, addr.ToString()));
}

Thanks Mike. I will try that. The server IP address I am trying to capture is a client's. This client is using our web service. We want to allow only a certain range of IP addresses access to the web service. Marcy

That is new information and not what I gave you. From your perspective the Server "is" a client. The client IP is in the HTTP Header. However the server is likely behind a firewall in which case you will only get the firewalls IP and there is nothing you can do to see behind the firewall.

This is likely based "per company"? If so the firewall IP should work fine for you. http://msdn2.microsoft.com/en-us/library/system.web.httprequest.userhostaddress.aspx[^]

I missed that... my bad. In the future post ASP.NET questions in the ASP.NET forum[^], this would have been answered in about 10 minutes over there.

Sorry, I wasn't sure, since it was regarding a web service and SOAP Header. I thought it would go in the XML forum. Thanks for the information. I really appreciate it.
