Sometimes people ask to visit places that they have no business visiting.  And, sometimes that craziness must be stopped.  Did you know you can load up an iRule and redirect DNS traffic based on the requested domain name?  Did you also know you can build out a fully-functional web page in an iRule.  All this (and more) are at the heart of what is known as "Blackhole DNS".  Check out this edition of Lightboard Lessons to learn all about it!

Nice article, John. I'm thinking about incorporating this example into our DNS course.
