@payown @stevenscott PiHole, yes. Two pi 4's both with PiHole on, one as a fallback.
Don't even need to use exit nodes at all if you tell Tailscale that you're using custom DNS from the admin panel, and I put the Tailscale IP's of my pi's in, with even further fallback from quad9 dns so there are four name resolvers in there. First two are mine, last two are quad9's, if my home internet connection drops out for whatever reason.
