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.
