No, *you* want these things. I do not, and imposing them is not in the interests of users in general. > Otherwise the number of very unpleasant surprises, including > stuff like this: > > http://www.theregister.co.uk/2011/06/30/xbox_swat_police_rait/ Nowhere in this article does it say that the user had a static IP address. And as I indicated earlier, even with a dynamic IP address, there are frequently other ways to find a host's IP address. If you force all hosts on a home network to have dynamic IP addresses, you break applications that need stable addresses. If you don't force all hosts on a home network to have dynamic IP addresses, those that don't need stable addresses can still get ephemeral addresses via privacy addresses, DHCP, or other means. You keep arguing for the perpetuation of bad hacks because of accidental properties of those hacks. I'd rather have well-designed mechanisms that are tailor made to suit particular purposes.
