I would like to see an automated conditional forwarding for Fritz!Box.
If it is recognised during the installation that the current DHCP server is a Fritz.box, a setting could be made to automatically set the IP address here.
I think this function would be useful for most German users.
I don't use "Conditional Forwarding" at all (even if I could with my non-fritzbox here in southwest-germany ) because I don't like the device names that my family gives them (pupsikakkasschlaufon, iphone, iphone, dings, bumms, …) so I rely on my own "IP address management" and use only "static" IPs for known devices (MAC1=IP1, MAC2=IP2, …) and each IP gets an entry in my Pi-hole (Local DNS Records) with a name of MY choice (name-iphone, name-laptop, name-tablet, othername-iphone, etc.)!
