I am using PtokaX in my college intranet to create a DC++ hub..but i do not keep my system on everytime..first of all i made a hub on PtokaX hub and distributed my computer static ip to my friends..When i turn off PtokaX,i want that all users to be connected to my hub to be redirected to another computer hosting a hub and also new users who connect with the ip of my machine to be redirected to the new running ip
Then you need to use some dns service and change ip everytime when it needs to point to another hub ...
