I have a testnet that has been running for several months. We have had several nodes from different locations connected. The blockchain has more than a millon blocks right now. Syncing a node from scratch is not working that well.
After enableing the -debug=net paramter I can see it is trying to connect to very very old nodes that do not exist any more or they had dynamic IPs. How to remove these IP's ?

2018-09-14 17:30:25 net: connection to xxx.xxx.xxx.xxx:xxxx timeout
2018-09-14 17:30:25 net: Connection not established
