Playing with Pi-hole  and PiVPN  on a VPS and learned about the Pi-hole Remote iOS app  on the subreddit . Wow, it’s really nice! 😍
Looks like the dev also made an app for AdGuard Home 😯
Pros: increased security due to leveraging threat intelligence feeds across multiple providers.
Cons: latency is coupled to the slowest resolver, and decreased privacy due to sending DNS requests to multiple 3rd party resolvers (rather than one or even none w/ something like Unbound).
I wonder if this idea has been implemented anywhere...
