I have a handful of different wifi SSIDs set up on my network at home to help with this, some route their DNS queries through a pihole instance and others (say, without the “AB” for ‘adblock’ suffix on their ssid names), don’t. Each ssid is their own vlan and each has their own dhcp listening that doles out the pihole instance address on the Adblock-enabled nets.

It’s easy enough to just connect to a different ssid if I see anything breaking, but it’s rare enough that I keep it connected to the pihole/adblock network at all times. Works super well.
