In which file are the credentials / IP-Adress / Path stored?

[muddiver]

Hi folks!

i need to change the IP-Adress of my NAS / Pihole, cause i messed up to use a IP that is NOT in the DHCP-Range,
so i want to change the IP-Adress which i entered in MoOde as Sambashare.

I had problems when the NAS was down booting MoOde was veeeery slow, maybe i was too impatient...
So i am a bit anxious that Moode will not boot when i change the IP-Adress of the NAS.

I thought the best way to change the IP Adress is to boot up all MoOde devices, change the IP of my NAS, do a reboot of my router to redo DHCP lease.
Change the IP-Adress in both MoOde devices, finished.

Can someone tell me in which file the credentials and the IP-Adress is stored onto the system?
So my last change if something goes wrong is to apply changes to the file via ssh.

Has someone experience with using a device with fixed IP onto the device IN the DHCP-Range?
I am unsure if i can fix the IP-Adress in my router AND turn the static IP onto the device on.
The whole thing is about the dns-server.. My pihole is connected via DHCP, which gives the Piholedevice the DNS of Pihole..
Nice loop......
I have the possibility to change the IP to static AND change the DNS fixed to Cloudflare.
But i see no possibility to stay in DHCP AND change the local DNS-Server manually..
