It's a bit frustrating that problems this old and well-known can
actually be used to cause damage.

The easiest way to check if you are vulnerable to DNS poisoning is to
try to poison yourself. Try my "poison yourself" page here:

  http://ketil.froyn.name/poison.html

It tries to redirect www.example.com to a fake IP (the same one as I
host my website on), where I have a virtualhost for www.example.com with
a plain html page. It'll tell you if you were poisoned.

Cheers,
