  1. Will the following line of code always return a unique machine name in a web farm, or it could sometimes return nothing/duplicate name?

    string currentRequestWebFarmNode = Environment.MachineName;

  2. Also, is IP address for each web farm node obtained by using code below going to be unique always in that web farm? My guess is yes, but not sure.

    string currentRequestWebFarmNode = System.Net.Dns.GetHostEntry(Request.Url.Host).AddressList(0).ToString();

The answers to these questions will depend on your hosting environment. The fastest way to find out is probably to try it.

  • I was looking for a fool-proof way of obtaining a 'unique' value for either IP address or machine name in a web farm. You think that may not be possible? – Sunil Nov 28 '13 at 23:49
  • I actually strongly suspect that it is possible. I just can't tell you what either of those expressions will return because it's based on how those machines are configured. – j__m Nov 28 '13 at 23:53
  • Ok. FYI - I was developing a generic framework where I needed to get a unique name for the current request's web server. That means my code will have to work in all web farms. – Sunil Nov 29 '13 at 00:00
  • Environment.MachineName seems like a reasonable name, but there's no way to guarantee uniqueness. – j__m Nov 29 '13 at 00:03
