So do you mean the ip address changes during running or the taskmanager failed and relaunched with a same hostname, but the ip address is different?
I am not sure the TM registers to JM with hostname or ip address. We could confirm that from @Zhijiang. For the NAT, currently Flink could not work well with NAT. Since the taskmanager do not provide a bind host/port for others to connect. There's some tickets to track this problem[1].
