I'll also point out that, despite the baseless claims of those who've  
asserted that IPv6 somehow provided a 'defense' against worms due to  
the large address space, those of us who think about these things  
have known about every single one of the techniques discussed in this  
paper and talked about them at length.  Messrs. Bellovin, Cheswick,  
and Keromytis simply wrote them down; no research was required in

'hints' which worm writers may use; also note that none except ND are
