This patch changes the NetworkClient behavior to resolve the target node's hostname after disconnecting from an established connection, rather than waiting until the previously-resolved addresses are exhausted. This is to handle the scenario when the node's IP addresses have changed during the lifetime of the connection, and means that the client does not have to try to connect to invalid IP addresses until it has tried each address.
