Stop using the same DNS for every device (do this instead to block ads and boost speeds)
Most people point every device at the same DNS resolver, but the article explains why you should tailor DNS per device role. For example, use ad- and tracker-blocking resolvers to clean up a [[Smart TV]]’s interface—options include [[NextDNS]], [[AdGuard DNS]], and [[Control D]]—and employ family-filter DNS like [[OpenDNS FamilyShield]] or [[Cloudflare for Families]] to sandbox kids. For chatty or insecure IoT gear, run a DNS sinkhole with [[Pi-hole]] or [[AdGuard Home]] (or a cloud service) to drop telemetry; pair it with router firewall rules for stronger containment. Performance-critical devices like phones and PCs benefit from fast public resolvers such as [[Cloudflare]], [[Google Public DNS]], or [[Quad9]]. The piece also notes hardware and router examples like the [[Unifi Dream Router 7]] and recommends matching DNS to device purpose rather than using a one-size-fits-all setup.
