If I have one static global ip server (netmaker sever) and 3 dynamic global ip servers (as netmaker normal node, global ip will possibly change when server restarts) on netmaker network called "awesome", should I make "relay server" for 3 dynamic global ip servers? or Hub and spoke type "default" netmaker network do the job for me when nodes global ip changed? (like propagate newly acquired global ip to rest of the nodes)
