For this you are right. If that IP isnt available then your cluster wouldnt be reachable. So you counter this by having the nodes create they're own ip that can be shared. I have my nodes on 10.0.1.10-15, and i use a Keepalived (check here and herefor info) service to claim 10.0.1.5 and use that as the target for my forwarding. It works by designating a "master" which claims the ip and having other slaves running on the other (specifically manager) nodes. When they lose connection to the master, another takes the role, claims the IP from the DHCP server and starts accepting the traffic. The equivalent in kubernetes is MetalLB i believe, for those that are interested.
