I think best is to start with a fresh Pi-OS lite image.  
OOTB without Pi-hole installed or any changes made, below one should resolve to an IP address first:

```auto
$ dig +short install.pi-hole.net
aws-ls-lon1.pi-hole.net.
18.169.210.144

```

If not, you have networking issues that are not related to Pi-hole.

Above only applies for pre Pi-OS Bookworm releases.  
Bookworm and above use **NetworkManager** instead of **dhcpcd** which can be configured with below (Network Manager Text User Interface):

`sudo nmtui`

EDIT: Some hints about prepping a Pi:

> I noticed some users asking for more detailed instructions for installing Pi-hole on a Raspberry Pi or another Linux setup. As I was in the process of reinstalling both my trusty Pi 1B's with Raspbian Bookworm and the latest Pi-hole v6 release, and usually I document the steps, I thought why not share here. Both Pi's have served Pi-hole reliable for over eight years now, still running on the original SD cards, and I think they have many years to come. As its a headless setup, I'll be doing so…
