For this reason I think that the transfer statistics that John shared before can be discounted in this discussion.<div class=""><br class=""></div><div class="">Thanks,</div><div class=""><br class=""><div class="">

In this case I'm talking about bad actors who provide false information to ARIN to get large block sizes, and then turn around and lease them to third parties.
