I can't see how "pure" DNS would affect routing as all it does is translate name to IP (and back maybe). If different DNS's resolve differently that may affect things.

You could try the tracepath command which works a little bit differently and doesn't need root privileges on UNIX/LINUX. This can show if packets are fragmented and highlight asymmetric routing though the latter isn't always the problem it used to be.
