I am busy with an action to remove all ip-adresses from my code and use hostnames that are registrated in /etc/hosts.
This works for lot of code and nodes , but not always..
Now the problem.
I have a function node that looks for the local ip and the ip of the active flow.
When the subnet matches it adresses the msg via mqtt and otherwise it sends the msg with i http command to another servr. This works for years.
But now i use host name for the localadress and dns name for http adress and i cant matched thse two anymore...
Is there a way in NR to resolve
a) a host as pecified in /etc/hosts
b) dns name the main parts works ok!
