resolv.conf in the host machine: 127.0.0.1 or 1.1.1.1?

Hi friend,

Stupid question :-)

I have a raspberry (headless) as a home server with Debian, docker and a lot of container.

One of these is adguard home which works well, I put in my router the raspberry ip as dns server and my home network now is safe.

I have this doubt:
in /etc/resolv.conf on the host (I'm talking about Debian on raspberry) now I have as nameserver 127.0.0.1.
It works... but I'm thinking... if the adguard home container were to go down... and if I were out of home... the server would become unreachable from remote because it would have no internet connection... so..it wouldn't be correct to set as nameserver in resolv.conf 1.1.1.1 and 8.8.8.8? Am I wrong?
The server which shouldn't need it the adguardhome filters... or yes?
Tanks
