Or possibly maybe Peter M. Gleitz's and Steven M. Bellovin's idea of "Transient Addressing for Related Processes: Improved Firewalling by Using IPV6 and Multiple Addresses per Host" http://www.cs.columbia.edu/~smb/papers/tarp/tarp.html A /64 per host is probably not necessary, however if an end-site has a /48, that's 65K hosts so it wouldn't likely be much of a problem for most sites ... certainly not my house currently or in the forseeable future or my current employer, or most employers I've worked for in the past. -- "Sheep are slow and tasty, and therefore must remain constantly alert." - Bruce Schneier, "Beyond Fear"
