Hmm. OK thanks @jfb
[root@fedora-iot-rpi ~]# ping 10.88.0.1
PING 10.88.0.1 (10.88.0.1) 56(84) bytes of data.
64 bytes from 10.88.0.1: icmp_seq=1 ttl=64 time=0.248 ms

The ping works when I run from the rpi itself. What I don't understand is where this IP is being set. Maybe it doesn't matter?
I'm troubleshooting the pihole and not sure where to look to get it working. I'm dealing with a Vodaphone Gigabox router that doesn't allow the DNS or DHCP changes as outlined in the docs.
Even manually configuring DNS per client doesn't seem to work.
