most hubs are not available to me.they have changed ip adresses

i have not used dc++ for sometime due to family illness,when i went in to try and download music,most of the hubs would not connect,most said ip adress was not available,or they have a new ip adress but there is no way to find it as i can't sign in to the hub,,how can iget back in to my hubs? or how can i get into some new hubs? that would be nice,so i could find some new music.ty

Use the publichublist to search for the hubs if you can remember the name of the hubs or in your case, search for music hubs, just use the filterfunction.
Another way is to use usersearch on one of the hublist's sites if you have the name of the OP's or other users in those hubs and try to track them down that way if you would like to return to same hubs. :)
