I got one r-pi zero running pi-hole at .220, and another pi-hole on a server dockerized at .221.
If that server goes down, another server has a dockerized pi-hole that takes over the .221 IP.
The failover is handled with keepalived.
At parents house they got one r-pi set as DNS 1, and 9.9.9.9 as DNS 2.
