This way you will have always a static IP address on your mobile host. There are other posibilities like mobile IP extension or multipath TCP or even some experiments splitting node's IP address into location and identifier halves.

You assign your own private addresses to them and use them in scope of your host and virtual machines running in it. > * I don't understand why my Xchat should loose connection, when I am > switching from ethernet to WiFi (and they are both available during > interim period). > The reason is that processes usually work with transport adresses (e.g. a TCP) and these include network address (e.g. an IP). And network addresses in the current Internet are used as locators, thus they depend on the network topology. > The type of network connection is just implementation detail, so why > this does not work?
