On the flip side, however, I would point out that attackers have had vastly more resources made available to them in part *because* IPv4 has been so easily scanned and abused. To be sure, a lot of viruses have spread via e-mail spam and drive-by downloads, and sparse addressing will not prevent script kiddies from banging away on ssh brute force attacks against www.yoursite.com. But there's been a lot of spread through stupidity as well.

A randomly setup ssh server without DNS will find itself brute force attacked. Darknets are setup specifically for detection of scans. One side effect of v6, is determining how best to deploy darknets, as we can't just take one or two blocks to do it anymore. We'll need to interweave the darknets with the production blocks. I wish it was possible via DHCPv6-PD to assign a block minus a sub-block (hey, don't use this /64 in the /48 I gave you). It could be that darknets will have to go and flow analysis is all we'll be left with.
