can somebody please give me new adresses for addnode?

You don't need addnode can leave it blank had 12 connections. Also you don't necessarily have to send the coins to another adress, all you have to do is backup/extract the privatekey(s) of your Netcoin adress(es) (which i advise you to always do anyway and backup the wallet.dat aswell just to be safe).
Backing up the privatekey you can do via the console help->debugscreen. For extracting the privatekey the wallet needs to be completely unlocked if your wallet is encrypted (NOT encrypted can skip this) so type in console:

lockwallet
walletpassphrase 600

Now that the wallet is unlocked you can extract the privatekey by typing in the console:

dumpprivkey

!!! You need to do this for every single adress you want backed up and keep it safe because if someone got a hold of your privatekey they can steal your coins!!!!

Importing the privatekey into the new wallet you can read in this thread previous page or on http://forum.netcoinfoundation.org/thread/814/guide-import-paper-wallet-private

Make sure you always have the wallet from a official source so or the Netcoin github https://github.com/netcoinfoundation/netcoin or the infosite http://netcoinfoundation.org/!!!
