DNS of the server where ASP.NET application is run

How to get to know DNS name of the server where ASP.NET application is run?

I want to get string "www.somehost.com" if my application URL is http://www.somehost.com/somepath/application.aspx

Is there some property of Server, Contex, Session or Request objects for this?

Thanks!

From stackoverflow

• The HTTP_HOST server variable can give you what you need.

  Request.ServerVariables("HTTP_HOST")
  

  Paul : That[s the host from the http headers. If there's a reverse-proxy or something in front of the ASP.NET application server, it's probably not the name of the machine that's running the ASP.NET application

• This will get you the DNS IP for the server that is hosting the web site

  void GetDNSServerAddress()
      {
          NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
              foreach (NetworkInterface ni in nics)
           {
            if (ni.OperationalStatus == OperationalStatus.Up)
            {
             IPAddressCollection ips = ni.GetIPProperties().DnsAddresses;
  
             foreach (System.Net.IPAddress ip in ips)
             {
              Console.Write(ip.ToString());
             }
            }
           }
      }
  

  However, while writing this ive just seen your edited post, so i think this is what you are after is simply:

  string host = Request.Url.Scheme + "://" + Request.Url.Host;
  

  Hope this helps!

• You can also get the 'machine name' using

  System.Environment.MachineName
  

  Alexander Prokofyev : No, it's for NetBIOS name.
