Error message - IP address seems to have changed. Unable to listen on 'ns_1@10.xx.x.xxxx'. (Underlaying POSIX error code: 'nxdomain')

what causing this error message ?
I am having 3 nodes cluster v4 .
with xdcr to 6 nodes cluster of v6.


‘nxdomain’ means that the network call is searching for a domain that can’t be resolved. If you have your cluster configured to use fully qualified domain names and then have a DNS issue of some sort, this may occur. One workaround would be to be sure at least the name on which you want it to listen is resolve-able by putting it in the hosts file or the like.

if I will create the cluster with the IPs and not DNS names it will solve the problem as well , yes ?
