Adguard Home with blocklists.

Is it ok to use my ISP DNS servers? I have primary pointing to what Adguard suggested, secondary pointing to Slingshot.

why would it not be?

Because part of the requests will be protected by the rules, and the other requests will just go through? So why have AdGuard at all?

Why don't people use their ISPs DNS servers?

They're almost always going to be closer/faster than Cloudflare or Google.

I can understand if you're using them for say, Ad filtering or Adult content blocking because you don't want the DIY hassle.

But why would you manually use 1.1.1.1/8.8.8.8 (standard, unfiltered public DNS) over your ISPs?

It can't be speed, because almost all home CPE will run a caching resolver anyway (and as mentioned, your ISPs name servers are probably closer therefore faster)
You'll almost certainly get better on-net CDN performance as well from using your ISPs NS.

Do people think they're getting privacy from what their ISP can see? Something else?

[At home I run AdguardHome with just the OISD List - no other lists - pointed to my ISPs nameservers]

I think it all steams from a few ISPs in the early days injecting ads in their DNS.

But agree, unless it's for filtering, use your ISP

I don't remember of specific New Zealand examples, but the last I've heard of this was so far back, and mostly US-based DNS, that I find this to be a non-reason.

I remember in US having to add comcast certificate to trust in order to get a home connection working. Very odd way of doing it.

Also if anyone remembers vodafones dns servers going down all the time I’m not surprised people use third party services.

Your asking becuase you think its not ok to use it for what ever reason.

Your internal network points toward your adguard instance, your adguard instance points towards your ISP DNS servers, that way you get the swiftness of their server and their CDN and the blocking of adguard.

AdGuard home hosted on two Raspberry Pis with config syncing between them. They both have my ISPs DNS as their primary upstream DNS and fallback to 8.8.8.8.

How do you sync the config? Is there a script or tool you have?
