As I've been migrating my sites to IPv6, each site gets its own IP. Works great. I did find that I needed to improve my tools so I could track the individual IP addresses and assign the appropriate DNS names to them, as I took several dozen (it's a small machine) sites and put them on IPv6. Other than not wanting to go to the effort to change all the config files, it's hard to think of a reason to share IPv6 addresses for anything. Virtual hosts were specifically invented to conserve IPv4 addresses; they don't provide any added function. R's, John PS: Well, there is my spider trap at http://web.sp.am which would be hard to do without using a shared IP. But that's perverse.
