Initially I did not use reuse_files, and indeed I did verify that the 
JSON files were indeed deleted and re-created every time when starting 
ipcluster.  So this was not the issue. 

How does IPcluster obtain the hostname/IP address of the controller if 
not specified? Because this is a local lan, the assigned IP's from the 
DHCP server are in the 192.168.0.* subnet and there is of course no 
DNS/FQDN. My problem was that the specifications in the config files 
seemed to be "ignored"/overridden by the internal ipcluster methods to 
assign the hostname/IP. Does it look at /etc/hosts? This has of course 
the specification of for localhost.
