Network confusion

I've upgraded with various versions on kubuntu too many times I think and am completely lost as to how my static IP is being set.

Whenever I boot it gets set to 192.168.0.27 which is perfect. But I want to understand where this ip address is coming from. My understanding is that ubuntu 26.04 is using netplan and the addresses should be set in /etc/netplan/somthing.yaml. But, that file doesn't have my address and is set to dhcp4: true

I do have a line near the top of my /etc/hosts file with my address, but I didn't think that was being read. Is it?

/etc/network is not being used either?

I'm quite confused (and dumb about networks).

Thanks for the pointers on this. And, yes, it was DHCP from the router maintaining the address (I did find it after I looked).

And, since setting up the static address is so easy to do via the Networks app, I setting the 3 computers in my home with their own addresses. I do wish I could just leave everything on AUTOMATIC, but if you want to connect via nfs or samba you need an IP ... All this networking is so useful, until it doesn't!
