9% is reasonable. I've got pretty strict filters on my home DNS and it's currently blocking 12%. I imagine that number would be much higher if I didn't have ad block extensions on all my browsers and IoT devices on a restricted VLAN.
Nope! NextDNS blocked 913,294 of 10,287,370 queries over the last 3 months. I'm sure the percentage would rise if I flipped on other options that they provide ("AI-Driven Threat Detection", "Block Newly Registered Domains", etc.), and I should probably revisit those.
Wow! I'm more intrigued by the fact that you did 10M queries in 3 months. I'm going to assume you're using a single profile for everything. I have separated machines/robots (that includes the TV), kids, and other profiles for business devices.
That's a steller idea, thanks for mentioning it! I didn't realize that different profiles assign unique DNS servers, allowing me to partition off devices that don't support DNS-over-TLS/DNS-over-HTTPS/IPv6. I don't think it'd affect total queries, but tighter rules for machines/robots, etc. should increase the percentage of blocked requests.
