[https://www.icann.org/resources/pages/dnssec-what-is-it-why-important-2019-03-05-en DNSSEC] allows your client to verify that, one, it is indeed my servers responding to your query and, two, that the data hasn't been modified in transit by a third party.
=== Optional adblock ===
Adblock is available but, personally, I would recommend using a local solution like [https://addons.mozilla.org/firefox/addon/ublock-origin/ uBlockOrigin] on desktop, [https://adaway.org/ AdAway]
on mobile (requires root ), [https://blokada.org/ Blokada] on android (without root) or [https://github.com/M66B/NetGuard/blob/master/ADBLOCKING.md NetGuard] firewall on android with adblocking ( without root). This feature is powered by [https://pi-hole.net/ Pi-Hole] and blocked domains are listed in [https://nixnet.services/hosts.txt hosts.txt]. The list is generated by [https://github.com/hectorm/hblock hblock].
