Note that as has been pointed out again and again on this list, Mr.
Pollard's scheme leaks namespace and is, in fact, a blueprint for how to
engage in cache poisoning. Please do not follow his examples- they
provide no discernable benefit over the standard method of doing this,
and in fact may inject harm.

RFC 2317 is easy to read and follow, and it works. If you want the quick
and dirty summary, have a look at
