// Checks that an IO error in sending a request to D2, results in ddns updates
// being suspended. This indicates that Dhcp4Srv's error handler has been
// invoked as expected. Note that this unit test relies on an attempt to send
-// to a server address of 0.0.0.0 port 0 fails, which it does under all OSs
+// to a server address of 0.0.0.0 port 0 fails, which it does under all OSes
// except Solaris 11.
/// @todo Eventually we should find a way to test this under Solaris.
