One of method missing is doing top down random walks of ip6.arpa.
That's only easy if delegation were on a per-nybble basis, which is commonly not the case. Because there are not typically NS's at every nybble level, you have to do more than one hex digit's worth of randomness in the scan in order to find a next-level delegation, increasing the cost of scanning that namespace quite a bit. (Having delegations at every nybble level would be ... alarming at best, given the amount of PTR redirection that implies. :) -- -- Todd Vierling <tv@duh.org> <tv@pobox.com> <todd@vierling.name>
