[QUOTE="SeriousHoax, post: 1118429, member: 78686"] Adding big DNS filters on mobile devices might not be a good idea as it would consume more power. AdGuard usually don't recommend anything but their own AdGuard DNS filter on mobile devices. Also on AdGuard for Android, default block rule for DNS filters is "Refused" (This will change in the future). In refused mode, when a dns query is blocked, the app/service/website most of the time will send many more requests. AdGuard will have to block all these attempts and fill its log with same blocks. It is also the reason why AdGuard on Android shows comically large amount of, "Blocked" and "Data Saved" number. In AdGuard for Windows, default block rule for DNS filters is "0.0.0.0" which minimizes too many DNS requests for blocked queries. So at least on mobile devices it is better to use DNS services like NextDNS, AdGuard DNS, ControlD, etc. where you can use big DNS filters like OISD, Hagezi, etc. On PC using a couple of large DNS filter lists had no impact on browsing performance for me. If other DNS like Cloudflare/Quad9 are noticeably faster than NextDNS/AdGuard DNS in your region, then one could use local DNS filters in AdGuard. One thing I noticed that AdGuard DNS filter has some regex rules to block any websites that resolves to the IP addresses defined by the rule. NextDNS cannot block these. AdGuard DNS can block those. I don't know if ControlD can. [SPOILER="Example regex rule"]/(https?:\/\/)213\.32\.115\..{100,}/[/SPOILER] [/QUOTE]
