 Summary: Better error message from Dns.GetHostByName
 
 Dns.GetHostByName throws SocketException with an error "No such host is
 known".  It should be changed to include the hostname that was being looked
 up so that when it comes out of the bowels of some library call it is
 informative.

+This is the same behaviour as MS - and there is a good reason for
+this: information disclosure. The framework doesn't know (and can't
+assume) under which context the application is executed. So leaking
+this information is potentially dangereous.
+
+The "right" way to fix this is at the application level. If the host
+name isn't sensitive then catch the exception and display a more
+appropriate message (or rethrow the same exception with a more
+informative message).
