Changing IP address

[gfreccia]

Hi All!

Where is it possible to manage the IP address of the server?
I've changed on etc/network/interfaces but I can access home page only; DNS resolution doesn't work.

Thank you!

IP address of what server?

Sorry, I was not clear!
The IP of AdGuard.
I've installed it using DHCP and now it runs only with the DHCP IP.
If I try to change it manually (e.g. on etc/network/interfaces) it doesn't work.

Thanks!
