JeBe came across a rather innovative way of determining if the codebase is running in a development or production enviornment. The logic goes, if there are two IP addresses, and one of them is 127.0.0.1, then it must be a development machine. And how do you check what the IP addresses are? It's quite simple, actually ...

private static string LocalAddress
{
  get 
  {
     string local = null;
     MatchCollection Mx = 
        Regex.Matches(RunCommand("cmd", "/c ipconfig"), 
           "IP Address[^:]+: ([0-9]+[.][0-9]+[.][0-9]+[.][0-9]+)", 
           RegexOptions.Singleline|RegexOptions.IgnoreCase);
     if(Mx!=null) 
     {
        foreach(Match Mc in Mx) 
        {
           if(Mc.Groups.Count==2&&Mc.Groups[1].Value!="127.0.0.1") 
                 local = Mc.Groups[1].Value;
        }
     }
     return local;
  }
}
private static string RunCommand (string Command, string Parameters) 
{
  ProcessStartInfo psi = new ProcessStartInfo();
  psi.FileName = Command;
  psi.Arguments = Parameters;
  psi.RedirectStandardOutput = true;
  psi.UseShellExecute = false;
  Process p = Process.Start (psi);
  StreamReader sr = p.StandardOutput;
  string s = sr.ReadToEnd(); sr.Close();
  return s.Replace("\r\n", "\n");
}

Although, I think the author used the System.Net namespace and iterated through Dns.GetHostByName(Dns.GetHostName()).AddressList, we still may have had a WTF ...
