IIRC, you need to ensure reverse lookup for DNS matches your nodename

Hi

I'm using dynamic nodes with "slurmd -Z" with slurm 23.11.1.
Firstly I find that when you do "scontrol show node" it shows the NODEADDR as 
ip rather than the NODENAME. Because I'm playing around with running this in containers 
on docker swarm I find this ip can be wrong. I can force it with scontrol update however 
after a while something updates it to something else again. Does anybody know if this is 
done by slurmd or slurmctld or something else?
How can I stop this from happening?
How can I get the node to register with the hostname rather than ip?

cheers,
Jakub
