+1 for NextDNS. Have been using them for years for blocking ads but also helped me troubleshoot some issues, as I could live track DNS queries by device.<p>Note the free plan is great for several devices <i>as long as they’re not Apple</i>. For some reason, 2+ Apple devices blow through the 300,000 query limit really easily. When I used a Pixel 2 I think it averaged 60,000 and fit in the quota with my other devices, and when I switched to iPhone it pushed the total over 300,000. But they’re cheap and definitely worth it.
