For IP. It appears to work, plus the TBTF blurb postulates an innaresting
approach for defending the existence of this distribution capability by using
the MPAAs tactics against it (should they attack).

From the TBTF article...

Distributing DeCSS via DNS. Unwrap the following and utter it on one line to
a Unix shell on a machine that is live to the Net:

                      dig @138.195.138.195 goret.org. axfr |
                        grep '^c..\..*A' |
                        sort |
                        cut -b5-36 |
                        perl -e 'while(<>){print pack("H32",$_)}' |
                        gzip -d

What you'll get, streaming to STDOUT, is the source code for the DVD CSS
decryptor...
